Application: dolphin (1.6.1)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

While browsing some folders, the mouse hovers for about 0.5 sec. on a file and Dolphin crashes.
It doesn't happen everytime the mouse lingers on a file or folder.
It doesn't happen on the same file/folder everytime.
More often than not, image and audio files are involved, but it happens with other types of files as well.


- Custom settings of the application:

View mode: details  (didn't try another)
Preview: unchecked
Sorting: Name, Folders first
Panels: Places, Information, Folders

Checked:
Startup -> Editable location bar
Startup -> Show full path...
Startup -> Show filter bar
Navigation -> Double-click...
Navigation -> Open folders during...
General -> Use common view properties for all folders
General -> "Ask for Confirmation When" group: all checked
General -> Show previews: Folders, Images, Do not create previews for local files above 5MB
General -> Context menu: all checked
General -> Status bar: all checked

The crash can be reproduced some of the time.
