Comment (by Alex):

 The issue here is the storage of the foreign key on the Aggregation
 object, which is created here:
 
http://code.djangoproject.com/browser/django/trunk/django/db/models/fields/related.py#L86
 (line 90).

Comment (by russellm):

 Interesting bit of history - #7506, fixed in [7773] logged a similar
 problem. Might give some pointers as to the possible cause.

Comment:

 This is just an ordinary bug, not a feature. I think it can miss the 1.1
 beta.

 I'm using the latest version from svn (as of 1-4-09) and python2.5.  I'm
 trying to pickle a QuerySet that is using annotate and I'm getting the
 following error:
 {{{
 raise TypeError, "can't pickle %s objects" % base.__name__
 TypeError: can't pickle function objects
 }}}

 Here is what I'm trying to do:
 (ProductChannel has OneToMany relationship with ProductChannelImage)
 {{{
 pc = ProductChannel.objects.filter(supplier=supplier)
 pc = pc.filter(status='new')
 pc = pc.annotate(num_images=Count('productchannelimage'))
 ...
 request.session['pc_qs'] = dumps(pc.query)
 }}}

 Before I added the annotation to the query it was pickling just fine.
