Hi,
I don't get this error if I run your code. Maybe the irrelevant code
causes the error: my guess is that there's a parenthesis mismatch or an
undeindented line.
Btw, calls to set_pending_list will fail since the name "message_list"
is not defined in its scope. Please follow Chris Mellon's advice.
Cheers,
