I'm unable to reproduce this. The supplied code simply works.
I've also done this implementation in production code.

Could be caused by OS X (as I'm on Linux), or a conflicting method between the 
parent class and the interface. Although in the latter case I would prefer a 
nice error message.
Could also been only in CVS.

Closing this bug since the original submitter cannot reproduce it, nor can I reproduce it on any currently-supported version of PHP.
