Hm, a ConnectionStateError again.  Sometimes just restarting the
instance helps.

A missing mime type.  The mime type registry needs to be correct
first; only then can all portal transforms work.  This particular mime
type is added during the plone migration.  So if you get that running,
this problem should go away.

Alternatively, you could delete the mime type registry as well and add
it again.  I have never done that myself though; same for the Portal
Transforms.  In case it goes wrong: you do have backups, right? :)
