[Zope] Installing Zope 2.5.0 Stable release and Python 2.1.2

Hi, according to this page: http://www.python.org/2.1.3/ Python 2.1.2, version which Zope 2.5.0 uses, has a bug which causes Zope to crash. So, I just wondering which python source should I install for Zope 2.5.0 stable release. Or perhaps Do the two hotfixes for Zope 2.5.0 correct it? Thanks in advanced, Josef.
