Bug 282092

Application: rekonq (0.7.0)
KDE Platform Version: 4.6.2 (4.6.2) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:searching for vintage guitars when I clicked on a link the page loaded but when I clicked back the links were not live, in other words when I moved my mouse over them there was no hand.

The crash can be reproduced some of the time.

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