Bug#473584: UserWarning: Module _mysql was already imported

[mentors.debian.net owner]

Package: python-zopeinterface
Version: 3.3.1-5
Severity: important

Bear with me if this package is not the cause of this problem. I'm not sure either.
I have a Python application that ran well on Etch but gives me a warning on Lenny.
In ipython it was simple to reproduce:

In [1]: import MySQLdb

In [2]: import twisted.internet.reactor as reactor
/usr/lib/python2.4/site-packages/zope/__init__.py:19: UserWarning: Module _mysql was already imported from /var/lib/python-support/python2.4/_mysql.so, but
/var/lib/python-support/python2.4 is being added to sys.path
  import pkg_resources

If I switch the import order then everything is well.
