Bug 289239

Application: dolphin (1.7)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I browsed files in split view mode and when closed the split view to single dolphin crashed.
Does not happen everytime.
This has happened with and without having the Terminal panel opened.


- Custom settings of the application:
View mode is Detail
Preview is on
Show hidden files is on
Show Toolbar is on
Show Menubar is off. Dolphin's menubar is shown nonetheless as my menubars are handled through the  Window Menubar widget inside Panel.

The crash can be reproduced some of the time.

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