Comment 3 for bug 462254

I have uploaded python-schooltool_2009.04.17-2 to https://edge.launchpad.net/~schooltool-owners/+archive/ppa/+build/1312575

You may need to manually resolve dependencies. Choose to upgrade python-schooltool and downgrade python-zope.component to version 3.4.0 from SchoolTool PPA.

Doing so would fix the exception posted in paste.log

Please try and reply if the server now starts, sudo /etc/init.d/schooltool-2009 start
