-- Information about the crash:
- What I was doing when the application crashed: it appends on many sites which use js or flash, like http://www.placeaupeuple2012.fr

- Custom settings of the application: javascript enabled (when it is disabled, there is no problem)

The crash can be reproduced every time.
