View any page and then go back, either by pressing the back button or delete, crashes the app completely but leaves OS X fine. 

Happens on several other sites as well, but seems most reproducible on forums.

GreaseKit appears to be responsible for this.
6   info.8-p.GreaseKit            	0x176f9b01 JSValueForKey + 175
7   info.8-p.GreaseKit            	0x176f6b62 -[Info8_pCMController evalScriptsInFrame:force:] + 401
8   info.8-p.GreaseKit            	0x176f6f18 -[Info8_pCMController progressFinished:] + 124

If it still crashes after uninstalling GreaseKit, please reopen this bug and attach a new crash log.
