[Zope] Failed to import class atoi from module ZPublisher.Publish

[Gabriel Genellina <gagenellina@xxxxxxxxxxxxxx>]

Hi

Yesterday we upgraded from Zope 2.4.0 to 2.5.1 (binary release, python 2.1, 
win32-x86), python 2.1.3, win32) ZServer/1.1b1
and now, I cant access some folders, error is always the same:

Error Type: SystemError
Error Value: Failed to import class atoi from module ZPublisher.Publish

Traceback (innermost last):

SystemError: (see above)

I've been able to track the error to the SQLMethods contained in the 
folder. Every folder that had an SQL Method inside can't be accessed.
Any attempt to access a string property (title, meta_type, src, 
arguments_src) of an SQLMethod gives the above error.
Only old SQLMethods are afected (objects converted from 2.4 to 2.5); new 
SQLMethods work fine.
