Bug 301353

Application: rekonq (0.9.1)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- Unusual behavior I noticed:

e' una perdita di tempo dato che ho firefox come browser predefinito pero' rekonq si apre comunque quando utilizzo kmail e choqok

The crash can be reproduced some of the time.

-- Backtrace:
Application: rekonq (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
