Try printing repr(ims), type(ims) and id(ims) then compare that with
repr(None), type(None) and id(None). My guess is you have a string whose
value is "None":
% python2.4

>>> int("None")
Traceback (most recent call last):

ValueError: invalid literal for int(): None
The output in 2.5 makes it more clear what you've got:
