Posted on his behalf because he doesn't know how to swim.

Lol! Gratz man, not often that bug reports make me laugh :)

Fixed for next release.

As a general rule, please do not post bugs from other people which you have not personally confirmed. The humor helped here, and it was trivial for me to verify this one, but I really don't trust bug reports from people that haven't been vetted through forum membership.
