*Before* the migration the whole mimetypes_registry is totally broken,
I can't click on it. I guess it's normal. If, just for the sake of
experimenting, I install it before the migration, I can click on it,
but the icons inside it will be broken (because the image URL-s return
HTML pages instead of PNG/GIF-s), and I couldn't fix that by
reinstalling it, and the migration will fail on the usual way. *After*
successful migration (that happens only if I delete all the custom
AT-based objects) the mimetypes_registry looks OK.

Well, I have a couple of ideas (and hair) left...
Still, anybody happens to know, to recapitulate my previous mail:
While migrating to 2.1, why the BaseUnit.mimetype doesn't implement
Products.MimetypesRegistry.interfaces.MimeTypeItem, where the said
BaseUnit object is the value of an AT field in an "old" object (whose
class extends BaseContent, and uses BaseSchema+Schema(...), previously
used successfully with AT 1.2.5-rc4)?
