[Comment from a bug triager]
From bug 258043:
- What I was doing when the application crashed: 
Trying to delete a "Gas Object" which was resized couple of times. some "Gas particals" were out of the red box (the box which shows the boundary of the particals). I think the particals should not have been out of the boundary box, in the first place.
