Application: dolphin (1.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.33.5-124.fc13.i686.PAE i686
Distribution: "Fedora release 13 (Goddard)"

-- Information about the crash:
Dolphin stops responding when I single-click a file to open it -- sometimes. It has done this opening images with Gwenview and text documents with Kwrite.

It does not do this if I right-click and select the program to launch the file.

If I go out for coffee and come back, the file will have launched, and Dolphin will be responsive again.

If I become impatient and use the taskbar to close Dolphin, Dolphin segfaults, and the file launches immediately afterward.

The crash can be reproduced some of the time.

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