Could you give more information how to reproduce this error?

And does the problem still occur in the latest test build?

Attachment: test case

This test case reproduces the described problem for me with ff3.0 but not in either a 3.1 or a moz-central debug build.  [Load the page and then immediately open the javascript console; if the problem is happening the error will be there.]

I do not know if a more complicated test case would still trigger the problem in ff3.1.
