All good except for the patch description, which says "infallible and handled" instead of "fallible and handled". :-) (Made me stop and look.)
Ahhh, annoying! Sorry about that!

I verified the bug on Windows 7 32bit using Firefox 34 Beta 2 (buildID: 20141020184313) and it seems to be fixed (no crash occurs). 
I'll keep an eye on Soccoro in the next couple of days to ensure that no crashes will occur before changing the Status of the bug.
Checking Soccoro no other crashes were noticed on FF34.0b, FF35 and FF36 versions on the latest 4 weeks post fix.
