I don't know much about the internal workings about 'vacuum'. My
guess is that there is something wrong with one of the indexes in
your db somewhere. I would try and rebuild them - starting with the
ones involved in the view. You might have to drop and re-create them
- as well as the view.
Good luck,
Chris
