It crashes about half the time when I log out/shut down. Note: I have patched libdbus to fix the crashes caused by its lack of thread-safety (using the patch that is likely to go into D-Bus 1.4.0). The crash can be reproduced some of the time. -- Backtrace: Application: Nepomuk Service Stub (nepomukservicestub), signal: Segmentation fault [KCrash Handler] #6 0x00007f8a7289372c in QMutex::lock (this=0x1c8e668) at thread/qmutex.cpp:150 #7 0x00007f8a6c0fd714 in QMutexLocker::relock() () from /home/kde-devel/kde/lib/libsopranoclient.so.1 #8 0x00007f8a6c0fd676 in QMutexLocker::QMutexLocker(QMutex*) () from /home/kde-devel/kde/lib/libsopranoclient.so.1 #9 0x00007f8a6c0fa88c in Soprano::Client::SocketHandler::~SocketHandler() () from /home/kde-devel/kde/lib/libsopranoclient.so.1 #10 0x00007f8a6c0fa950 in Soprano::Client::SocketHandler::~SocketHandler() () from /home/kde-devel/kde/lib/libsopranoclient.so.1 #11 0x00007f8a728973b4 in QThreadStorageData::set (this=<value optimized out>, p=0x0) at thread/qthreadstorage.cpp:148 #12 0x00007f8a70512f7a in qt_cleanup () at kernel/qapplication_x11.cpp:2581 #13 0x00007f8a704a4f8c in ~QApplication (this=0x7fff57d9d520, __in_chrg=<value optimized out>) at kernel/qapplication.cpp:1088 #14 0x00007f8a719d1e8b in ~KApplication (this=0x7fff57d9d520, __in_chrg=<value optimized out>) at /home/kde-devel/src/KDE/kdelibs/kdeui/kernel/kapplication.cpp:879 #15 0x00000000004040df in main (argc=2, argv=0x7fff57d9d958) at /home/kde-devel/src/KDE/kdebase/runtime/nepomuk/servicestub/main.cpp:100 Reported using DrKonqi 994813 1 trueg 2010-07-27 14:36:44 +0000 does this still happen with soprano 2.4.64? 994840 2 alex.merry 2010-07-27 15:11:47 +0000 It hasn't happened for a while now, so I guess not. It doesn't happen with r1148427 soprano and 4.5 branch KDE, at any rate. 995410 3 trueg 2010-07-28 16:26:45 +0000 Marking as fixed following last comment. 1050104 4 leviatan1 2010-11-27 15:35:31 +0000 With kubuntu 10.10 and kde 4.5.1/2/3 sometimes nepomukservicestub crash with Segmentation fault, always on shutdown/reboot. I can't get a backtrace, kde is closed and Drkonki fails to improve the trace. 1053412 5 andresbajotierra 2010-12-04 15:48:57 +0000 [Comment from a bug triager] There are new reports with similar backtraces which may be related: bug 252062, bug 258689, bug 258744. May be they are related ? Regards
