Application: dolphin (1.7) KDE Platform Version: 4.7.00 (4.7.0) Qt Version: 4.7.2 Operating System: Linux 2.6.38-11-generic x86_64 Distribution: Ubuntu 11.04 -- Information about the crash: - What I was doing when the application crashed: Dragging a JPEG file from my home folder to a message composition window of Mozilla Thunderbird causes Dolphin to crash. The crash happened as soon as I dragged the file over the task manager widget in my custom toolbar (set to auto-hide). This crash does not appear in any case, sometimes everything works as it should. The crash can be reproduced some of the time. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault [Current thread is 1 (Thread 0x7f699db74780 (LWP 2236))] Thread 3 (Thread 0x7f698b6e9700 (LWP 2237)): #0 0xffffffffff60014c in ??
