Created attachment 483027 [details] Backtrace With the new "aw, snap" notification, if you try to close a crashed tab the chrome process segfaults. Backtrace attached.
Could be a duplicate of bug 603680.
Looks like the same underlying problem, yeah. Should be easy to repro, will dup if appropriate.
I couldn't repro this on my machine, though I did fing another bug that I now can't repro either.
Still can't repro this, but the other crash was bug 604282. Was this in an opt build?
I'm about 99.999% sure this is a dup of bug 603680. Please reopen if you can repro. (I couldn't ever, with the steps here.)
