Give us more details about the problem, does it crash frequently or just that one time, what are you doing when it crashes, what OS do you have, have you made any changes to your computer recently etc?
Seconded, though you may never actually find a reason why other than with what Adam has asked above.
And as the report asks in the Detail section: What were you doing just prior to the crash?
(sometimes here I'm doing nothing more than moving an entity.)
