Bug 279289

Application: rekonq (0.7.0)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

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

Just wanted to start Rekonq but it immediately crashes. Reproducible always so Rekonq does not start at all.

Work around - remove all Rekonq application data and configurations.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
