Comment 15 for bug 213948

Just some more info about its reproducability:
https://www.bwin.com/ crashes without fail approximately 3 seconds after the page seems to have finished loading, this happens in forground and background tabs, with and without mouse action
http://youtube.com/ crashes infrequently, always upon loading a video (i.e. if the video has started, you're safe), reloading the same video will not reproduce the bug

various other sites crash very rarely: http://www.miniclip.com/ http://www.megavideo.com/

flashplugin-nonfree 9.0.124.0ubuntu1
firefox 3.0 3.0~b5+nobinonly-0ubuntu1

hope this helps
