The bug is initially described here http://aspnetwebstack.codeplex.com/workitem/616, but it seems it should be reported in the Discussions section. 

Hi Max,

The issue tracker is definitely the right place to report bugs. The team will take a look at it and make a decision on it. Of course, we always welcome contributions to MVC and if you want to try your hand at fixing it yourself, that would certainly be welcome too! We have lots of information on the wiki on how to contribute.

Thanks,

Eilon
