Does that wall have any thickness? That's often one of the problems.

Yep that seems normal to me. They're going reflect the environment which in this case includes a blue backdrop. I'm guessing there are 3 walls and no ceiling. Is there a particular reason why you changed it from the default black?

Long shot but is it not to do with the number of bounces you've got with raytracing for any area lights you may have, I think that if they are set to 1 it bounces then only gets the background colour as it dosent know what it is from the bounce.
