Wow, I've never seen one that short!
It looks like there's missing from /System/Library/Frameworks/Accounts.framework/.
I woud go ahead and apply the 10.7.5 COMBO Update, and see if that doesn't fix it:

1) downloading Pacifist
2) downloading Safari for Lion (safari6lion.pkg)
3) Opening safari6lion.pkg in Pacifist
4) deleting StagedFrameworks/Safari/ folder which can be found under: System/Library
5) copy and paste StagedFrameworks/Safari/ from the opened safari6lion.pkg in Pacifist.
Hope this helps others
