[apport] scim-launcher crashed with SIGSEGV in QTextCodec::fromUnicode()

[mumismo]

Binary package hint: scim

Scim starts up automatically with gnome.
Just updated to 7.04 beta 1 and the first boot. Anyway scim is working ok, so I think that maybe it has tried to load twice and the second one crashed.

The crash only seems to happen when scim and skim are installed together. Uninstalling skim helped me (and I can still use scim for my usual input methods), but that won't be of much help if you absolutely need to have scim load at startup.

Incidentally, I tried adding scim at startup, but it still loads scim-launcher twice (no crash, though).

Sorry, I should have clarified that my own problem is on Kubuntu 7.04.

Don't worry about this, it's normal to have two scim-launcher process.

I think it's because one launcher connect the real scim backend with the
socket frontend, another launcher connect the socket backend with the
X11 frontend. But I'm not really familar with the scim code, so it may
be wrong.

That's okay. It will be a while before I fully understand how everything works in Linux, but that sounds about right to me.

Thank you very much, Ming.

[Olivier (olidel)]

Hello,

    I have exactly the same problem (symptoms) and I'm also running kubuntu with skim.

Thanks.

O.D.

Now we are having 15 duplicates of this bug, yet not much idea what the problem is. As the crash seems to be related to KDE and skim, it may not be simply a scim bug.

There are three parts involved: skim, scim and (likely) scim-qtimm. Also Qt 3 in Ubuntu is patched to make scim-qtimm work. Any of these parts can be the source of this bug. i am not saying it's not scim's fault, but it's quite complicated and we need to figure out what the real problem is.

For now all I can do is marking new bugs as a duplicate of this, and as it seems no other Ubuntu developer is subscribed to this bug, its chance of getting fixed is quite small. You can help by help analyzing this bug a bit more, and/or asking skim maintainers and KDE people to look at this bug.

[foxbunny (bg-branko)]

FWIW, I ran openSUSE 10.2 with skim-scim package (configured
automatically by YaST) and it had no problem. I don't know if the
openSUSE dev team patched any of the components (I am no dev, so I
don't know how to check), but it is probably worth investigating.

In the sake of clarification, it doesn't crash *everytime* on kubuntu neither. I eventually happen to get CJK input works in KDE-Kubuntu, altough it wasn't as straightforward as it could be. (And i'm still unable to get CJK input in ooffice, but that's another issue). The times it crashed was during the install time, maybe because it's not clear which packge you exactly need in order to get CJK input (scim, skim, language-tools, etc ?), thus i may have installed in-compatibles packages.

Hi

This problem came to me when I changed my desktop from gnome to kde ...

some gnome programs still in kde .

thank u :)

[Nicolas Piguet (npiguet)]

This basically happened to me while I was following the wiki guide to install chinese on Kubuntu (https://help.ubuntu.com/community/SCIM/Kubuntu?action=show) on an en_US.UTF-8 locale. Whatever I do, I've never been able to get chinese input working under Kubuntu/Kde, it works fine under Ubuntu/Gnome though...

[Nicolas Piguet (npiguet)]

Oh, and given the number of reports of this bug, and how crippling it really is for people that need CJK input, may I suggest to raise the priority of this bug a notch?

Greetings, Nicolas!
I'm sorry! I'm using Kubuntu Feisty Fawn. The developer replied me that this
bug is a duplicate of 88179.

This is the message from the developer:

Hi, Nicolas.

I don't think this bug is critical. In fact, SCIM ran well on my
Kubuntu FF box after I've sent the first report (disabled notification
after two occurences).

BR,

Branko

Speaking of Kubuntu, it's a shame that disabling SCIM does
not restore standard Konqueror arrow navigation
(especially Alt-left for Back)

In my opinion, raising bug priority without anybody working on it, or
anyone committed to work on it, doesn't really achieve anything.

Would you please file a separate bug for this issue with more details?

Thanks,

in my case the error happened on Hardy. My system has a lot on it, and may or may not be representative of most systems. I have several window Managers installed to play with as well as full KUBUNTU, Xubuntu and Standard Ubuntu meta-packages.

[Rolf Leggewie (r0lf)]

Thank you for reporting. I wonder if this old issue may be fixed in 1.4.9 which is about to be released in Karmic. Please verify.
