[Moin-user] 'module' object has no attribute 'expat' whensavingfrom gui editor

[David Cramer]

Well, when I switch to python 2.5.1 using the method described below, I
get a 500 Internal Server Error once I change /bin/python to point to
python 2.5.1.

Is there something else to do when switching to a new python version? Or
is there some documentation on watch involved in upgrading python from
under an existing moinmoin install?

Thanks,
David
