CC Jacek: Jacek, any technical comment on crashings with this kind of log? Hopefully we can rename the bug to a more common summery to avoid duplicates, thanks!
This is a known limitation of Gecko, which uses 'main thread' concept that makes a group of objects usable only from the thread that initializes Gecko. It's a hard problem that I don't have good solution for yet.
However, such logs may be caused by other reasons as well. Please attach mshtml,ieframe,seh,tid logs so I can verify that.
