Application that crashed: k3b Version of the application: 1.66.0 KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 139" Qt Version: 4.5.1 Operating System: Linux 2.6.27.23-0.1-pae i686 Distribution: "openSUSE 11.1 (i586)" What I was doing when the application crashed: I was able to reproduce the crash several times: 1) Open a directory in the K3B filesystem browser 2) Delete this directory from another program (Krusader in my case) This causes K3B to immediately crash. -- Backtrace: Application: K3b (k3b), signal: Segmentation fault [Current thread is 1 (Thread 0xb4714700 (LWP 17539))] Thread 3 (Thread 0xb132fb90 (LWP 17587)): #0 0xffffe430 in __kernel_vsyscall () #1 0xb7bdef62 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #2 0xb7c3e0f9 in ??

Created attachment 34542 [details] bt full log for crash from bug 196509 A more verbose backtrace using "bt full"
I can also confirm this crash.
I suppose I should also add that I'm using K3b 1.66.0 alpha 2 on KDE 4.3.00
Could you check this bug on current trunk? I cannot reproduce this, maybe it's already fixed. Thanks
