Comment 7 for bug 203250

I have been unable to reproduce this crash (though I have suffered others), and upstream haven't taken much interest in debugging, it seems. As a result, I'll have to mark this bug as Invalid, but if you encounter it again, please re-open the bug. If it would be possible, please upload the full crash report next time; it includes more detailed retracing information.

I do recommend that if you have not already done so, you open a bug on Thunderbird.
