I updated my django version to revision 9710 today and now I am
getting the following error message on screen:
Caught an exception while rendering: subquery has too many columns
This is the traceback:

ProgrammingError: subquery has too many columns
It seems that this query is creating the problem:
groupmembers = requestedgroup.group_members.exclude
(id__in=groupadmins)
And the model looks like this:
group_members = models.ManyToManyField(User, verbose_name="group
members", related_name="groupofumembers")
And ideas?
