Version: (using KDE 4.4.0) OS: Linux Installed from: Ubuntu Packages (The Crash Reporting Assistant refused to submit a bug report for this. I don't know what you guys think, but if an application crashes, I believe it's a bug. I followed the instructions for installing the debug symbols, so if it's not enough... then please tell me what I need to do.) I was previewing, opening, and deleting image files in my home directory. After deleting five or so files, Dolphin crashed. Here are the stack traces: Application: Dolphin (dolphin), signal: Segmentation fault [Current thread is 1 (Thread 0x7f3d55ed47f0 (LWP 26243))] Thread 3 (Thread 0x7f3d4496b910 (LWP 26289)): #0 pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:220 #1 0x00007f3d3ee12c91 in ??

I reproduced it after viewing/deleting five more image files, this time while running it in Valgrind.
