Hrm, not enough to go on from the backtraces, and I can't get this to repro though I've added most of those add-ons -- is there any way to repro from a clean profile?

Chris: Will try again to repro. After I installed something else and restarted, I crashed again. So I have the browser in a state where it is crashing in this stack, but I haven't yet been able to narrow down what the cause may be.

looks like this have been low volume on the trunk (0-4 crashes per day) since it might have first appeared starting on 20100918 with 1 crash on 4.0b7pre2010091804 In the last week its been showing up more consistently.

An interesting data point is the majority of other crash reports crashed with no extensions installed. I think I was the only one running with extensions.

This is another one where we want to be able to see the jitcode in the minidumps. I haven't looked at this dump, so maybe it is in fact there, but we're generally not seeing it in JM jitcode crash dumps. I'll check when I get time.
