Application: rekonq (0.8.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

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

Nothing.  I left the laptop on overnight, with several tabs open in rekonq, and during the night it crashed by itself.  I have seen this at least twice.  I presume there is a tab that is refreshing itself, and one of the refreshes must be crashing rekonq.

The crash can be reproduced some of the time.

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