[Rails-core] Naming clash

[Manfred Stienstra]

A few days ago we noticed some strange errors popping up on one of  
our applications, it turned out to be a rather nasty naming clash  
between a controller and an actionmailer.

I don't really have time to dig into all the rails internals to see  
where this is going wrong, perhaps somebody with a little bit more  
knowledge about the lazy class loading can pick this up?
