Application: plasma-desktop (0.3) KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2)) (Compiled from sources) Qt Version: 4.6.0 Operating System: Linux 2.6.30-1-amd64 x86_64 Distribution: Debian GNU/Linux unstable (sid) -- Information about the crash: Freequently the task manager goes mad and keep with an empty slot as it was mapping and invisible application. I still have no clue how to reproduce it, but it's happening with some frequency. I suspect about the konversation application, since I'm alway running it when this crash happens. But as I'm not sure about it, I still need to do more test which I'll report soon. Here is the list of the current applications (on the task manager) that I was running during the last crash: - Konsole; - Kontact (with KMail running) + KMail composer window; - Konversation; - Chrome browser in the other workspace. About task manager configuration: - Forcing only one row; - Only show applications from the current desktop; - Group by applications; - Sort alphabeticaly. The crash can be reproduced some of the time. -- Backtrace: Application: Plasma Workspace (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0x7f2429f287f0 (LWP 2975))] Thread 2 (Thread 0x7f2405a60950 (LWP 2976)): #0 0x00007f242784bb69 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #1 0x00007f2427af9471 in QWaitConditionPrivate::wait (this=0x19ea010, time=18446744073709551615) at /home/abner/Projects/kde/src/qt-copy/src/corelib/thread/qwaitcondition_unix.cpp:87 #2 0x00007f2427af8fce in QWaitCondition::wait (this=0x19e6f80, mutex=0x19e6f78, time=18446744073709551615) at /home/abner/Projects/kde/src/qt-copy/src/corelib/thread/qwaitcondition_unix.cpp:159 #3 0x00007f2428b91030 in QHostInfoAgent::run (this=0x19e6f60) at /home/abner/Projects/kde/src/qt-copy/src/network/kernel/qhostinfo.cpp:252 #4 0x00007f2427af8a82 in QThreadPrivate::start (arg=0x19e6f60) at /home/abner/Projects/kde/src/qt-copy/src/corelib/thread/qthread_unix.cpp:244 #5 0x00007f2427847f7a in start_thread () from /lib/libpthread.so.0 #6 0x00007f2425b9389d in clone () from /lib/libc.so.6 #7 0x0000000000000000 in ??
