The error you get is probably caused by the upgrade process not doing its job properly.
Can you tell me if you have a record in sf_meta_type_descriptions that looks something like this:
id - 445278DC-F303-4BEC-8589-E2A7446C610C
app_name - //
meta_type_id - 638670CC-B540-4FD3-ADB0-101899D1630A
user_friendly_name - Basic profile
description - NULL
voa_version - 1
Also you need a record in sf_meta_types with id equal to the meta_type_id above. We have some clients reporting that doing a fresh upgrade the issue goes away.
