This is a very interesting way of iterating over a dictionary ;)

n.Key == path will always be false here, because String.Equals
will *not* be called.

You must cast n.Key to string:

	(string)n.Key == path

Check your code for similar errors and if you still think you've
found a bug, please file a case in Bugzilla with a self-contained
test case anyone can compile.
