Hi Aahz!

I'm building my app on a 10.5.8 system, with standard versions of
Python and PyObjC (2.5, and 2.0 respectively). I have not determined
if the errors occur on specific versions of OSX, but we QA the
application on both Leopard and Snow Leopard and internally we cannot
reproduce the problem (yet).

The error posted is the full traceback. There is nothing else.

The value of entityNames is *always* the following:

entityNames = ['com.apple.contacts.Contact',
                   'com.apple.contacts.Email Address',
                   'com.apple.calendars.Calendar',
                   'com.apple.calendars.Event',
                   'com.apple.calendars.Recurrence',
                   'com.apple.calendars.Attendee']

The session is created using
"ISyncSession.beginSessionWithClient_entityNames_beforeDate_". The
prepareToPullChanges... code would not be invoked if creating the
session returns a nil/None session object, or if it raises any
exception.

Thanks!
