I've got the same problem this morning (1/16). The previous time I tried to
open an individual contact was several days ago and it worked fine then. I
have installed quite a few "High Priority" updates from Microsoft Update
during that time.

The error message I get as Outlook crashes is:
AppName: outlook.exe AppVer: 11.0.8118.0 AppStamp:456628bf
ModName: plugin.dll ModVer: 1.0.0.6530 ModStamp:42653320
fDebug: 0 Offset: 0000163b

I noticed "ModName: plugin.dll" in the error message and tried turning off
all plugins, but that didn't help. I also ran "Detect and Repair..." from
the Help menu and that process completed without complaint, but the problem
opening individual contacts remains.

I read the recommendation regarding cleaning up the Forms cache, which I
tried (even though I don't use Forms and no forms were listed when I clicked
Manage Forms) to no avail.
