I don't have extensions installed. Does it crash for you in safe mode?
Did you sent a crash report? see about:crashes

I tried running Minefield in Safe mode and I got the same behaviour.  Then I tried a clean profile and after a little while Minefield instructs me that a script is taking too much time:

http://watch.tsn.ca/js/OneClip.aspx:1655

If I let it continue, Minefield crashes.

As to crash reports, Minefield doesn't ask me to send any reports.

With the latest version

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b1pre) Gecko/20080906062345 Minefield/3.1b1pre

the crash is no longer there.
