Running Trac 0.12 on Ubuntu 10.04 - Error

Question

I've installed trac 0.12 on my ubuntu 10.04, running the tracd internal webserver. When i access the page at http://127.0.0.1/myTracProject, I get the error message:

You installed Trac 0.12? Your traceback shows "Trac-0.11.7-py2.6.egg". Looks like you need to do some cleanup.
