Mantis. 
Okay well once I got over the fact that I have to sign up for yet another internet account just to report a flipping bug, I tried to register. I used my hotmail address of course since that actually is my major email address (I've been a user of the service for years and have a 200mb file store, which they seemingly gave me for free). Then I read your note saying hotmail wasn't allowed. Then I tried to change the email address to my work one, which I hate giving out. THen I got a screen full of errors saying:

End result of the farting around. Bug not reported. Which is great, it means it doesn't need to be fixed. Mantis doing it's job well then.
