Could you run the strigi indexer in valgrind and reproduce this one? For that you have to disable the indexer in the nepomuk config: "kcmshell4 nepomuk". Then start it manually in valgrind: valgrind nepomukservicestub nepomukstrigiservice Hopefully it will tell me more.

Then start it manually in valgrind: It was already unchecked -- not sure if it was always that way, or is there something that would have it off when it crashed? Is there any other way the Strigi stuff could have showed up in the backtrace? > valgrind nepomukservicestub nepomukstrigiservice > > Hopefully it will tell me more.

If so this bug can be closed as > fixed since the crashing code has been protected with mutexes. I'm running the version 4:4.7.0a-0ubuntu1~natty1~ppa1 of the Ubuntu kde-runtime package. If it's been fixed since then, I apologize for the noise. I don't see "mutex" anywhere in the patches Ubuntu has applied, so I assume this fix hasn't been backported.
Closing this as a duplicate of bug 275880 since I am fairly certain that it can be the only source of the problem. Hopefully the patch I posted there does also solve this crash. *** This bug has been marked as a duplicate of bug 275880 ***
