[EuroPython] Registratrion: doubling of usernames

[Harald Armin Massa]

> I assume that you registered while you were unauthenticated?

That should not. I really digged up my password and logged in. I did not
check if I still was logged in when I entered my registration information,
but my steps where:

- I logged in
- I clicked on registration
- I entered my data
- I entered my payment - information
- I waited to get sent back to the europython-page
- I was provided with ghum1 and a new password.

Especially: the only reference to GHUM is my username within plone. So
"ghum1" must be created somehow out of ghum?

Let's dig for easter eggs,
