Bug 246957

Application: rekonq (0.5.0)
KDE Platform Version: 4.4.5 (KDE 4.4.5) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-gentoo-r1 i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I left facebook idle for a while on the public timeline. In another tab I had google mail open. When I came back to the PC, rekonq had crashed.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: rekonq (kdeinit4), signal: Segmentation fault
