Description of Problem:

Somehow MonoDevelop no longer likes my MonoTouch solution. When I try to build
the MonoTouch project I get "Build failed. Object reference not set to an
instance of an object".

When I try to clean it, I get this error message (I assume the errors are
related):

System.NullReferenceException: Object reference not set to an instance of an
object
