Application: dolphin (2.0) KDE Platform Version: 4.8.00 (4.8.0) Qt Version: 4.8.0 Operating System: Linux 3.3.0-0.rc4.git1.4.fc17.x86_64 x86_64 Distribution: "Fedora release 17 (Beefy Miracle)" -- Information about the crash: - What I was doing when the application crashed: I was draging some PDF-file to the auto hiding task-bar panel. Disabeling switching the panel from auto-hide to always visible solves the problem. The problem is always reproducable. But draging the file to some panel that does not containg the task-bar it sometimes crasches, and sometimes not. The crash can be reproduced every time. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
