What I was doing when the application crashed:
I had three tabs open. I opened a page with a flash movie and middle clicked a few links which loaded up in the background. I finished watching the movie and then was reading the surrounding information when the browser segfaulted and left 3 ophaned flash windows which closed a few seconds after.
