[KevinM (kevbert1)]

This problem occurred when I performed update and upgrade from the terminal. Kernel 2.6.28-6-generic #17-Ubuntu SMP Fri Jan 30 15:35:08 UTC 2009 x86_64 GNU/Linux with all updates to 14:00 UST.

[Thomas Schulz (tschulz)]

Same her, fresh installation of Kubuntu 9.04 Alpha 4

[Mitch Golden (mgolden)]

I have gotten this on every install of Jaunty from alpha 2 to alpha 4. Interestingly, I didn't get this on alpha 4 until I did an upgrade.

In prior alphas, for some reason the bug reporter wasn't properly sending this in (maybe it was a timeout on launchpad) so this is the first time I have ever made it this far.

[David (dtschaefer)]

Same for me, crashes after login

[Félim Whiteley (felimwhiteley)]

I upgraded to Alpha4 from Intrepid. IT worked fine for a while, did it's very first index, told me it had finished, I was looking about System Settings at Notifications panel when it crashed, probably 2mins after it had completed first index.

FWIW: The laptop is a Sony PCG-FX701 (i386 AMD Athlon processor).

[NeoFax (neofax99)]

Same problem on every boot in fresh Jaunty Alpha 4 with all updates up to 13 Feb 09.

[Mark Greenwood (fatgerman)]

Same here, every boot since install clean of Kubuntu Jaunty Alpha 4, on AMD64 and i386.

[ironstorm (ironstorm-gmail)]

Got this error after an upgrade from Intrepid to Jaunty done 2 hours ago.

[Shaved Wookie (shavedwookie)]

Is it just me, or has everyone who has mentioned their processor architecture said that it's all AMD64?

[patcito (patcito)]

Nope, mine is Intel(R) Core(TM)2 CPU T5600 @ 1.83GHz.

[Mitch Golden (mgolden)]

Mine is an antique Sony Vaio PCG-XG19 - sub 1GHz Pentium.

[spitfire (mieszkoslusarczyk)]

But it is a 64 bit capable processor;)
Are you running 64 bit ubuntu?

BTW I am.

[patcito (patcito)]

no, it's a 32 bit

[melwazeer (melwazeer)]

Good Day,
No, I am running 32 bit version. I do not know if it is 64 bit capable or not.

In my case I'm not sure if this problem occured on my Core Duo (64bit capable) or on my Atom (not 64bit capable). I guess on both ...
But I use 32bit on both systems anyway.

Are you waiting for KDE 4.2.1? Or do you want KDE users to switch to Gnome so you will have only to support mainstream Ubuntu? Say something. This silence is so frustrating. Please...

Problem appears right after clicking on "[ ] Enable Strigi Desktop File Indexer" at "Nepomuk/Strigi Server configuration" in systemsettings -> Apply.

Strigi Service is still not running.

[John O'Neall (joneall)]

I have this right after login on a 32-bit JJ alpha 4. It also seems to occur after a crash of something like Kompozer (which is another, more annoying problem).

[kabotage (kabotage)]

hi, it crashed again. I just upgraded jaunty to alpha 5.

[Vítor E. Silva Souza (vitorsouza)]

For a while now the "crashed with SIGSEGV" is not showing up after boot anymore. The services seem to be running fine (although I have no idea if these are all the services that are supposed to be running):

vitor@seattle:~$ ps aux | grep nepomu

I use Kopete and I have "Enable Strigi Desktop File Indexer" checked, although it says right under it: "File indexer is suspended". Don't know what that means.

Anyways, just thought I'd say that maybe the issue is fixed for me. If anyone wants any logging or debugging information from my system, feel free to ask. I'm running Jaunty and I do apt-get upgrades almost daily.

[Daniel Semblano (dsemblano)]

not showing anymore too

[Jonathan Thomas (echidnaman)]

Aurelien Gateau fixed this by turning off Nepomuk and nepomukstrigiservice by default in kubuntu-default-settings.
The crash would still be there if you turned it back on, but by default most people won't have the crash on startup unless they explicitly re-enable it.

[Belisarivs (v-pelcak)]

So it is fixed by disabling service?
Great.

Hi all,

I suppose, disabling the service is a temporary workaround
until the problem is found and fixed.

The "fixer" explicitly stated that the bug is still there.

It crashes trying to disable itself, so it's not that different than what would happen if there was no crash.

[Nikos Efthimiou (nikos-efthimiou)]

I crashed at suspend.

[Liviu Beraru (beraru-liviu)]

May I ask what does this application do after all?
What is it trying to do and what was it supposed to do?
I know this is rather a technical question, but I am insterested in knowing the answer.

[Daxar (ndaxar)]

Dear Liviu,

In fact I don't know what the application do. It appeared every time I
started KDE desktop. So I do nothing.
These days it doesn't appear, but I don't remember if I checked the option
"don't show this anymore. please!!".
I'm sorry i cant't help you more than this.

Daniel.

http://www.linux.com/feature/144853 is a readable explanation of what it is supposed to do. Basically it's just a way to put meta-data about your files and emails into a searchable database.

Chris,

Thank you for your links.
It look likes a great and very powerful tool, but I can see it works
"underground" yet, not as a "direct" tool.
I guess...

Bye,
Daniel.

Dear Beraru

I quote the copy of the relevant website and suggest you to go thru the same for an answer:

Nepomuk - The Social Semantic Desktop
Information Society Technologies

Project Objectives

Human knowledge work mainly consists of the reception, interpretation and structuring of information, the explicit articulation of thoughts in suitable representations (like texts and pictures), and the sharing, exchange and discussion of such resources with other people. The way people proceed in this is heavily influenced by the tools they use: The personal workspace - and the personal computer in particular - support and reflect the individual ways of information processing, thought articulation, and knowledge sharing across social and organizational networks.

NEPOMUK

NEPOMUK's Goal

NEPOMUK intends to realize and deploy a comprehensive solution - methods, data structures, and a set of tools - for extending the personal computer into a collaborative environment, which improves the state of art in online collaboration and personal data management and augments the intellect of people by providing and organizing information created by single or group efforts.

Social Semantic Desktop

This solution is called the Social Semantic Desktop. This enhanced personal workspace (the Desktop) will be Semantic since it will give information a well defined meaning, making it processable by the computer. It will be Social since it will support the interconnection and exchange with other desktops and their users.

Desktop Aspect

To build the Semantic Desktop, NEPOMUK's objectives are to develop the methods, data structures and services necessary

    * to annotate and link arbitrary information on the local desktop, across different media types, file formats, and applications. Semantic web data structures and techniques will be applied and adapted to achieve this goal.
    * to articulate and visualize the user's ideas and transform them into semantic information. We will extend easy-to-use wiki technology and integrate it with annotation mechanisms.
    * to integrate content creation and processing with the users' way of structuring their work. Key approach will be the integration of agile process modelling concepts with the information generation and structuring.

Social Aspect

To cope with the interconnection and exchange with other desk- tops and their users, NEPOMUK's objectives are to develop

    * tools for social relation building and knowledge exchange which support knowledge sharing within social communities. These tools will provide semantically rich recommendations, which allow members of a community to not only exchange documents and other isolated information chunks, but all relevant information about their context and the participating community as well.
    * techniques for distributed search and storage of information, based on scalable extensions of the distributed hash table technology and p-grid infrastructures, which allow efficient search over distributed information resources and provide a shared knowledge pool within a community.

Community Uptake

The idea of the Social Semantic Desktop will reach its full potential only if i...

@Chris Bainbridge, @ramadasan7:
Thank you so much for this information. Now that I have an idea what it is, I really want this feature. This is great software. I wasn't aware of the semantic desktop.
Thank you once again.

I had this options disabled for a long time and today i decided to enable them again. So what i did was enabling 2 options in Nepomuk/Strigi Server configuration :

Enable Nepomuk Semantic Desktop
Strigi Desktop File Indexer

And the problem occurred.... What I've noticed was that after pressing apply is that a Warning message occurs after "Strigi Service is still not running." but it disappeared very fast.

What i did next was disabled the option and then enabled them again to reproduce the problem, but this time i did manage to get a screenshot before the Warning message disappears. The message clearly says:

Failed to contact Strigi indexer (Could not get owner of name 'org.kde.nepomuk.services.nepomukstrigiservice': no such name)

After that message i went to PolicyKit Authorization in System setting and searched for any org.kde.nepomuk.... policy to Grant the authorization witch is needed but as i saw there is no such policy setting for nepomuk service.

Fixed in KDE 4.3. (And that's where all the dupes stop too, pretty much)
