Copy+pasted from OTRS ticket #2007071610010746:
I've tried today to create an account. I'm sure I already have one, but
there seems no way to find out what it is, so I tried to create a new one.#
All of the names I tried seem to be already taken, so I had to keep trying
new ideas- eventually, I got an error saying:
"Out of capcha images- this shouldn't happen."
I've also notified the person via OTRS about this bug report, so he can track it from here on.
