enabling TicketDeletePlugin causes internal error in Trac

[divil@…]

installed the TicketDeletePlugin with the easy_install command and enabled it in the trac.ini file

this is what Trac says after trying to open the project-page:

Oops...

Trac detected an internal error:

That sounds like an error in the PYTHON_EGG_CACHE setting, not an issue with the plugin. Please ask on the IRC channel or mailing list if you have more questions.
