Application: plasma-desktop (0.4) KDE Platform Version: 4.6.1 (4.6.1) Qt Version: 4.7.2 Operating System: Linux 2.6.36-gentoo-r7 i686 Distribution (Platform): Gentoo Packages -- Information about the crash: - What I was doing when the application crashed: In smooth tasks, I right clicked a task icon, and choose do display an application launcher while the application is not running. I then closed the application, plasma-desktop crashed and restarted after a few seconds. - Custom settings of the application: I placed the smooth-tasks widget on the plasma bar and removed the traditional window list. I've tried to set one application to show a launcher when it is not running. Plasma crashes as soon as smooth-tasks tries to show the launcher. The crash can be reproduced every time. -- Backtrace: Application: Plasma-Desktop-Umgebung (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0xb59c1710 (LWP 4145))] Thread 2 (Thread 0xabbf6b70 (LWP 4174)): #0 0xb772f424 in __kernel_vsyscall () #1 0xb60ea61e in poll () from /lib/libc.so.6 #2 0xb5b76d90 in g_poll (fds=0x90d2200, nfds=1, timeout=-1) at gpoll.c:132 #3 0xb5b6a98e in g_main_context_poll (context=0x909e718, block=<value optimized out>, dispatch=1, self=0x910bf30) at gmain.c:3093 #4 g_main_context_iterate (context=0x909e718, block=<value optimized out>, dispatch=1, self=0x910bf30) at gmain.c:2775 #5 0xb5b6ac7a in g_main_context_iteration (context=0x909e718, may_block=1) at gmain.c:2843 #6 0xb6e5f011 in QEventDispatcherGlib::processEvents (this=0x909e028, flags=...) at kernel/qeventdispatcher_glib.cpp:424 #7 0xb6e31def in QEventLoop::processEvents (this=0xabbf61d0, flags=) at kernel/qeventloop.cpp:149 #8 0xb6e32215 in QEventLoop::exec (this=0xabbf61d0, flags=...) at kernel/qeventloop.cpp:201 #9 0xb6d3b553 in QThread::exec (this=0x909da08) at thread/qthread.cpp:492 #10 0xb6e122dc in QInotifyFileSystemWatcherEngine::run (this=0x909da08) at io/qfilesystemwatcher_inotify.cpp:248 #11 0xb6d3e4b3 in QThreadPrivate::start (arg=0x909da08) at thread/qthread_unix.cpp:320 #12 0xb2087de7 in ??
