Application: rekonq (2.3.2)
KDE Platform Version: 4.10.80
Qt Version: 4.8.4
Operating System: Linux 3.9.2-1-CHAKRA x86_64
Distribution: "Chakra Linux"

-- Information about the crash:
- What I was doing when the application crashed: I was activating flashplugin to see a video on youtube. I had also other 2 tabs opened. The plugin didn't manage to load so I tried to close Rekonq but it crashed. 

- Custom settings of the application: I have activated the "click to load plugin" option, sometimes when I try to load flashplayer rekonq crashes; more often with a video on facebook, rarely with a video on youtube.

The crash can be reproduced sometimes.

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