I haven't heard of this *specific* problem before.  I also don't see
how it can happen:

102         if claimed_at is not None:
103             claimed_at = datetime2epoch(claimed_at)
104         else:
105             claimed_at = _reactor.seconds()

The problem of catching exceptions is tricky - we can't match on
message text, as it can be localized.  And SQLAlchemy isn't very
specific in breaking db errors down to exceptions.

We can add an assert that claimed_at is not None, but I'm not sure
that will help.
