Application: plasma-desktop (0.3) KDE Platform Version: 4.5.00 (KDE 4.5.0) Qt Version: 4.7.0 Operating System: Linux 2.6.32-24-generic x86_64 Distribution: Ubuntu 10.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: I had accumulated a lot of notifications from three different applications. 1. Clicked on notifications icon (systray area) to view notifications 2. Clicked on each application button (at top of list) to show notifications from just that application 3. With the last application button still selected, clicked on 'X' at very top of list to clear all notifications 4. 'No new notifications' message (I think) superimposed over list, at which point Plasma crashed -- Backtrace: Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault [Current thread is 1 (Thread 0x7f29c6c48780 (LWP 1581))] Thread 2 (Thread 0x7f29a56f6710 (LWP 1589)): #0 0x00007f29c654ff83 in *__GI___poll (fds=<value optimized out>, nfds=<value optimized out>, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:87 #1 0x00007f29bb1504a9 in ??
