I think this is not hte problem since Ape creates the database tables
and its columns from scratch. You only must create the database. Anyway,
after inspecting the tables I show a lot of blob columns.

raises UnpicklingError
What column type are you using in MySQL? I would expect that you need
BLOB, but I have no experience with APE.

Hi all,
I have spent over two days testing the Ape product, and all the time I
become the error UnpicklingError, unpickling stack underflow .
Here are my results:
- Using a filesystem database works fine.
- Since mysql creates the tables as myisam (non-transactional) per
default after some failed tests I tweaked the code, so that the tables
are created as InnoDB.
- I have tried a fresh installed zope.
- I have put some LOG statements into the code and here is the log:

UnpicklingError: unpickling stack underflow
I think that the problem is that ape tries to unpickle the string
array('c') and fails.
Any clues?
Sorry for the long post, but I think it's worth the length.
