I experienced this crash while exiting fullscreen Youtube in Firefox 4, with Flash 10,2,153,1

[emptythevoid]

First time I've seen it. I was looking at an embedded Youtube video and double-clicked on it to switch to full screen. I then switched it back to regular webpage view and up came the error report. I couldn't tell anything unusual had happened except for the error report. Firefox didn't care and the flash video kept going as normal.
