Bug 301418

Application: dolphin (2.0.95)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.4.0-030400-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I went to Control → Help → About Dolphin
Then it crashed.

[Maybe just because I was running Dolphin from Project Neon (ie. Kubuntu daily master builds) inside my regular 4.8.3 session]

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
