looks like there might be several forms of the stack for the signature with the ranking looking something like below and the most frequent crash looking like the stack above.

since this happens so close to start up there really aren't any useful comment or urls.   code inspection might be the only way to guess what might be going on.

Comment 1

[Dave Townsend [:mossop]]

I don't see a single crash report for Firefox 4 so I don't think this should block.

> I don't see a single crash report for Firefox 4 

indeed. More recently, the crash signature seem to end at about Firefox 10. 
Looks like it continues as nsToolkitProfile::Release(). Do you agree?
For example bp-6a26d8e2-a55a-4070-9906-f66bd2130119 stack is similar to bp-f44b2b86-32d4-4a14-8847-d95c52130119

Several forms of the stacks mentioned in comment 0 still exist, such as
bp-6a26d8e2-a55a-4070-9906-f66bd2130119

2	xul.dll	SelectProfile	toolkit/xre/nsAppRunner.cpp:2075

Closing because no crash reported since 12 weeks.
