The crashes seem to occur on both Windows and Mac. cc'ing Jeff for comment.
There aren't very many crashes total (5, all on 36.0.3, in the last month). There are also 5 crashes reported for Thunderbird with the same signature.
I guess this shouldn't be "critical" then?
Closing since there's been no reports of this crash since April 28, 2016. Please reopen this bug if you can reproduce this crash in a current version.
