Actually, all you need to do is touch the file _db_storable and/or
_session_storable in the Minivend root directory. (You can set databases
and sessions separately to use Storable. DBM databases will need to be rebuilt
if you change _db_storable.)

Are you sure you didn't have a UserTag or GlobalSub using Data::Dumper?
I can't see where MV would cause this itself, and I run with it on
at least one high-volume site without crashes.
