pvmjpg21.dll crashes the shell

Hello. Not sure if this is the right group for this or not - hopefully
someone has seen this already.

When i hover over an *.avi file in explorer, explorer simply crashes.
I know this is related to pvmjpg21.dll, but not sure exactly what is
going on. Maybe its the tooltip triggering this?

Thoughts?
