I've got the same problem here as well. For me it seems to happen if I've been using xpand but I also have the Waves ssl bundle demo in my plugins folder that has expired. I think I remember it happenning before the waves demo though. It has expired anyway so I'll ditch it and try to narrow it down.
I know the other day I quit without the 'unexpected quit' message - but I also wasn't using any VI's (xpand) in that session. The only others that I've added lately is the vst wrapper (but took it out again) and Hybrid.

Cheers
Kim
