I added some print statements near the offending cursor.execute and for get_db_prep_lookup (note: expect line mismatch in traceback), here are the results:
{{{
exact pk= [u'33']
exact pk= [[u'34']]
sql=SELECT 1 FROM ""table"" WHERE ""id""=%s
params=[[u'34']]
}}}
clearly the found pk is being put on a list that breaks stuff. The models don't use any custom fields. The SELECT statement refers to the first of inline-edited objects.
