According to the backtrace you were in the middle of a drag and drop operation... do you remember something like that ? May be you dragged the taskbar entry ? This could be one of the Qt or X11 drag-and-drop bugs (like bug 219210, or bug 192000, when trying to add a new widget) Regards *** This bug has been marked as a duplicate of bug 192000 *** |
Application: plasma-desktop (0.3) KDE Platform Version: 4.4.67 (KDE 4.4.67 (KDE 4.5 >= 20100310)) (Compiled from sources) Qt Version: 4.6.2 Operating System: Linux 2.6.31-14-generic i686 Distribution: Ubuntu 9.10 -- Information about the crash: - What I was doing when the application crashed: Selected an item on task bar - Unusual behavior I noticed: Plasma's bottom bar re-started and crash dialog opened, the active window was OpenOffice, dolphin and google-chrome were running, I've selected chrome on the taskbar when the crash happened. Cannot reproduce again, this was a random crash. The crash can be reproduced some of the time. -- Backtrace: Application: Plasma Workspace (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0xb77ae700 (LWP 16885))] Thread 7 (Thread 0xabde9b70 (LWP 16890)): #0 0x003e6422 in __kernel_vsyscall () #1 0x00119e15 in pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/i386/i686/../i486/pthread_cond_wait.S:122 #2 0x022a1487 in QTWTF::TCMalloc_PageHeap::scavengerThread (this=0x23793a0) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:2304 #3 0x022a14d1 in QTWTF::TCMalloc_PageHeap::runScavengerThread (context=0x23793a0) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:1438 #4 0x0011580e in start_thread (arg=0xabde9b70) at pthread_create.c:300 #5 0x04e4f8de in clone () at ../sysdeps/unix/sysv/linux/i386/clone.S:130 Thread 6 (Thread 0xac5eab70 (LWP 17424)): #0 0x003e6422 in __kernel_vsyscall () #1 0x00119e15 in pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/i386/i686/../i486/pthread_cond_wait.S:122 #2 0x066ed317 in ??
