Well, we're going to need to fix that. Using a transaction here is
basically a bad idea IMO, and the current complaint shows that it
creates its own set of problems. Pointing at check_session_authorization
is no argument why it should be that way.

Without having consumed any caffeine, I'd wonder whether looking at
the "source" parameter would help resolve matters.
