Hi, everyone - it's been ages since I posted (I can't even remember the last time that I did) but I'm in desperate need of your help to solve this issue. 
It all began earlier this evening when I installed SIMBL and seemingly out of nowhere Dock.app began crashing at an alarming pace - a couple times per second actually! I've uninstalled SIMBL and tried reverting, but no luck.
I'm going to attach my crash report, and I'm well and truly praying that one of you clever bunch can help me pinpoint what's going on and how to fix it.
Thanks so much in advance!
