[ZODB-Dev] ZopeUndo.Prefix import problem

[Chris Withers]

Hi All,

Trying to go to the Undo tab in the ZMI for Zope 2.12.0a3 for one 
database I have gives the following on the storage server:

ERROR ZEO.zrpc (6397) can't decode message: 
'(K\x05K\x00U\x08undoInfo(K\x00K\x14}U\x0bdescription(cZ...'
------
ZEO.zrpc.Connection(S) (127.0.0.1:49396) Error caught in asyncore
Traceback (most recent call last):

     raise ZRPCError("import error %s: %s" % (module, msg))
ZRPCError: import error ZopeUndo.Prefix: No module named ZopeUndo.Prefix

However, this ZEO server has the following in it's zeo.conf:

<runner>
    python $INSTANCE/bin/py

..and this is copied and pasted from the shell:

$ bin/py

 >>> import ZopeUndo
 >>> import ZopeUndo.Prefix
 >>> ZopeUndo.Prefix.__file__
'/home/chris/buildout-eggs/Zope2-2.12.0a3-py2.5-linux-i686.egg/ZopeUndo/Prefix.pyc'

So I'm totally confused.

Anyone got any ideas?

Chris
