Thunderbird-3.0b3 doesn't close cleanly on Fedora 11

I just updated to Fedora 11 and got TB-3.0b3 in the package. It works,
but when I close the program it immediately pegs one of the cpu cores at
100% and stays that way until I manually kill the thunderbird process.
It even does this in "safe-mode" so I don't think it's an extension issue.

Anyone else see this, or have a fix/work-around?
