Description of problem:
While creating an app with rhc, it throws an exception.

NOTE: the application is created fine and is usable. The DNS _is_ setup correctly. I have no idea why this is throwing an exception.

NOTE: it doesn't seem to go through the retry period checking for the DNS to have been propagated.


Here is the debug output from rhc:
