Trac oops with getting known user

[anonymous]

I was on the virtualbox website. Already logged in I call the documentation website and get a trac oops:

Oops… Trac detected an internal error:

If you think this really should work and you can reproduce it, you should consider reporting this problem to the Trac team.

Go to ​http://trac.edgewall.org/ and create a new ticket where you describe the problem, how to reproduce it. Don't forget to include the Python traceback found below.
