Bug 257598

Application: rekonq (0.5.0)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.36-0.slh.8-aptosid-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
rekonq always crashes if I connect with the network at the TU Dresden library. It is a VPN internet access: You connect with an unencrypted WLAN hotspot (WEB/VPN), then you start a browser and enter a URL, it redirects to an authentication webpage where you have to enter username and password. rekonq crashes when this redirect happens.

The crash can be reproduced every time.

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