Yeah, I've had this one too :-( Dunno what's causing it but it also happens
if you have the names specified as parameters to the python script.

I think it's something to do with PS's calling the name if they can before
returning it. This is probably to make it behave like DTML but is a bad
thing in my experience, especially if calling the thing ends up recursively
calling the python script, which might be what's happening here.

Or I could be talking rubbish ;-)
