Annotate with "extra" triggers Traceback (bad SQL)

[ErikW]

I have a query which performs a fairly complex "extra query" (about 10 sub-select queries). When I added the annotate() call to the chain, I started getting the following traceback.

#select is a dict of SELECTS.
Profile.profilekeyword_set.select_related().filter(approved=True).extra(select=select).annotate(anchors=Count('keyword__anchor')).select_related()

It looks like a comma is being added after "keywords_keyword"."created" instead of a ")" (just a guess).
