[Zope] DBMaker adapter problem

[Mike]

Hi,

does anybody use DBMaker with Zope using Z DBMaker Database Adapter for
Linux2?

I've got a strange problem. Entering any SQL query on the 'test' tab I'm
having:

Traceback (innermost last):
    File /opt/Zope-2.1.4/lib/python/ZPublisher/Publish.py, line 214, in
publish_module
    File /opt/Zope-2.1.4/lib/python/ZPublisher/Publish.py, line 179, in
publish

[ blah blah blah ]

    File /opt/Zope-2.1.4/lib/python/Shared/DC/ZRDB/Connection.py, line
177, in manage_test
      (Object: RoleManager)
    File /opt/Zope-2.1.4/lib/python/Shared/DC/ZRDB/Results.py, line 104,
in __init__
  ValueError: unpack sequence of wrong size
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Thanks for advise,
Mike
