#31 — Cannot uninstall CMSNotification

Same here. I got the included backtrace immediately after uninstalling.

I restarted the instance after installation and the error appeared again. The only way to resolve the problem was to undo the action via the ZMI. I.e. uninstallation is impossible.

My Plone version:

    * Plone 3.3.2
    * CMF 2.1.2
    * Zope (Zope 2.10.9-final, python 2.4.6, linux2)
    * Python 2.4.6 (#1, Jan 10 2010, 20:00:44) [GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu4)]
    * PIL 1.1.6
