sr=me, but are there legit reasons mDocument would be null?  If so, please
remove the assert.

You might want to check out bug 166504 timeless and see if you still this
problem. I'm wondering if it may be the source of this problem as well. Actually
I wonder if it is just a symptom of another problem, that is causing the QI to
fail in nsXULButtonAccessible::GetAccState
