Description axrkde 2015-05-15 15:15:43 UTC

Application: dolphin (14.12.3)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: One file was currently selected. I pressed Alt+F4 twice in succession since the first press did not seem to register. I was then taken to the crash reporting assistant. 
Dolpin was opened from Konsole using xdg-open

The crash does not seem to be reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Thanks for the bug report! This issue is known already. It happens if opening a context menu freezes the application for a while (which can happen for different reasons which are outside Dolphin's control), and the application is closed while that happens. Unfortunately, it's not easy to come up with a clean and reliable solution because the nested event loop that is run by the context menu complicates the program flow considerably.
