Qt Version: 4.8.1
Operating System: Linux 3.2.0-34-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: i tried to download an attachment from gmail and it didn't

- Unusual behavior I noticed: program froze and the graphical interface was like overwritten with gray - didn't just turn grayer but pixellated gray

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