I've queried the downstream bug, though it may be hard to tell whether or not it is still around since Dr. Konqi can't catch nepomukservicestub crashes, and the Ubuntu crash handler that has been catching these has been disabled for final release.

For what it's worth, the downstream bug garnered one duplicate report from KDE 4.4.2.

Yes this crash can be reproduced in Lucid Lynx with KDE 4.4.5 (and even with KDE 4.5 RC2).
To give you a hint, this crash occurs when system language is set to Turkish language. When system language is reverted back to English, the crash dissappears and nepomuk+strigi works correctly.

Thanks for the response. It would be great if you could also follow the upstream bug here: http://bugs.kde.org/show_bug.cgi?id=232760 , as the nepomuk developer may need to talk with you for details of the crash, and direct communication is more effective than me relaying it between you two. ;)

Thanks in advance.

I am using Kubuntu Lucid Lynx (10.04) on two of my machines (a desktop PC and a netbook) with two different KDE versions (4.4.5 and 4.5 RC2) and this crash can be reproduced on both machines on every login. From my experiences as a user, I can confirm that this bug is alive since KDE 4.4 beta stages (started when virtuoso/soprano first introduced) and it never get fixed.

From my experiences, I suspect that this is mainly because this bug affects only some machines with some specific locales. I am using Kubuntu in Turkish (tr) and this crash occurs when system language (not KDE UI)is set to Turkish: Nepomuk crashes, strigi gets disabled and akonadi cannot be started, also Dolphin nepomuk interface disables too. And when the system language is reverted back to English, the Nepomuk, Strigi, Dolphin nepomuk tagging/search modules and Akonadi starts working perfectly.

As far as I can see this crash is also one of the main reasons of the notorious "nepomuk service not registered at D-bus" error which is mentioned again and again on Kubuntu and KDE forums but cannot be solved. Some translation strings (or, should I say character sets ???) not working corretly with soprano/virtuoso.

Now we are getting somewhere. But I need a better backtrace. The one in this export confuses me a lot since it seems to jump back and forth. At least I cannot make much of it.
Thus, I would ask you to
1. disable Nepomuk in the kcm: "kcmshell4 kcm_nepomuk"
2. make sure "nepomukserver" is running. If not start it via "nepomukserver"
3. run the storage service in gdb: "gdb --args nepomukservicestub nepomukstorage"
4. Get a backtrace from the crash that should occur and attach it here.

I am sorry, I am not very familiar with gdb. I failed to create a backtrace report with gdb. So I reproduced the crash with apport (ubuntu crash handler). It is a single text file with .crash extension and I hope it has all the debug information you need. I only changed the username to "username" for the sake of privacy. If it is not useful, I will try gdb again.

@ismail: The backtrace did help a lot. I managed to find a bug in Soprano. However, it is not related to this bug report. :) At least not the initial commenter's crash.

I have found out that this crash happens when the global LC_CTYPE variable is set to "tr_TR.utf8". I will also report this to KDE bugs. However, this bug may be Kubuntu specific. It is clear that nepomuk/soprano does not like tr_TR.utf8 charset. Nepomuk/Strigi/Akonadi runs fine with the below locale settings (this is the workaround I use):

LANG=tr_TR.utf8
LANGUAGE=tr_TR
LC_CTYPE=en_GB.utf8
LC_NUMERIC="tr_TR.utf8"
LC_TIME="tr_TR.utf8"
LC_COLLATE="tr_TR.utf8"
LC_MONETARY="tr_TR.utf8"
LC_MESSAGES="tr_TR.utf8"
LC_PAPER="tr_TR.utf8"
LC_NAME="tr_TR.utf8"
LC_ADDRESS="tr_TR.utf8"
LC_TELEPHONE="tr_TR.utf8"
LC_MEASUREMENT="tr_TR.utf8"
LC_IDENTIFICATION="tr_TR.utf8"
LC_ALL=

If LC_CTYPE is set to "tr_TR.utf8" then soprano crashes (On KDE 4.4+ Lucid) and also Dolphin won't open (on KDE 4.5.1 Maverick). So this is definitely a character set/soprano related problem

Hello Sebastian, I'm glad that the backtrace I provided helped you. By the way, Nepomukservicestub & soprana still crashes (With turkish Locale on KDE 4.5.1 Kubuntu maverick + Lucid). I have more information which might help you (I've posted the below information on Launchpad too, since I couldn't decide if this is KDE or Kubuntu specific problem)
