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: in rekonq, i had two tabs open, both reviewing KDE wiki information. I clicked on the X on one of the tabs to close it, and rekonq crashed.  At the time, I also had the BOINC client running in the background @ 80% cpu use & virtualbox w/a Win7-x64 VM running in background using 1536mb RAM for VM out of 4gb total system ram.

The crash can be reproduced some of the time.

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