Bug 290021

Application: dolphin (1.99)
KDE Platform Version: 4.7.95 (4.8 RC1 (4.7.95)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-7-generic x86_64
Distribution: Ubuntu precise (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I had the wesnoth addons dir open and downloaded some addons manualy, then I unpacked the addons via dolphin and searched via ctrl+i if I already had them installed.

After a few searches dolphin crashed with this backtrace

The crash can be reproduced some of the time.

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