Ok, I fixed the colon-before-indent problem.

I added some logging:

# Ignore changes that are not revision mod 200
def change_interval(change):
  log.msg("Examining change %d" % change.revision)
  if change.revision == None:
    return False
  if change.revision % 10 == 0:
    return True
  else:
    return False

Now I get this error:

2008-11-20 17:40:15-0600 [-] _finished : [Failure instance: Traceback: <type 
'exceptions.TypeError'>: int argument required
[...]
        master.cfg:73:change_interval

That's pointing to the log output.

If change.revision isn't an integer, what is it?  How do I extract an integer 
value to do comparisons?  The BuildBot documentation doesn't really talk about 
what a Change is.  Even the API docs are vague.

Thanks.
