Py2exe issue

[rcmn]

I'm using py2exe-0.6.9.win32-py2.6.exe

i used option 3.
On a list of 500 i get the same error than previous.
On a list of 250 once it just quit leaving the open file at 0k and on
the second attempt it failed with the same error and a note about
"TypeError: 'NoneType' object is not callable".
Basically totally random errors.
Obviously there is something that py2exe cannot bundle. because I have
been using this script(as *.py) more than 30 times now .And as long as
i respect the 500 window$ limitation. I had no issues.
