When I assign a bug on creation I get:
-------------------------------------------------------------
Traceback (most recent call last):

---------------------------------------------------------------------
this only happens if the bug has a change note.
if I create an item, and either add the change note or
assign after creation, it works fine.

I suspect this might be due to the fact that I don't
have a working mail server.  I configured my system to
"mock" email until I find the time to setup my mail server.

You can test against my server at:

But please notify me!!! (y.mor@ioe.ac.uk)
