Bug 253916

Application: dolphin (1.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
It helps if your test machine is slow and/or data is swapped out of RAM to disk. Open dolphin and right click a file, then immediately close the window (I hit the X in the top right corner). If the window closes before dolphin has had a chance to present the context menu, it will crash (taking down any other dolphin window with it).

I did this once by accident, then a second time on purpose, so it seems to be reproduceable. But it can be difficult to get the timing right - if the machine is fast enough the context window will appear practically instantly. Also, each time I tried it I had two dolphin windows open.

(One might suspect this is a Qt bug, but I wouldn't know. Please forward as appropriate.)

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
