In what way, other than its debug description, does it "not work"? Have you
tried actually using it?

Remember that "po" just asks the object to describe itself. NSURL objects
which were constructed relative to another URL describe themselves that way,
with the relative part and then the relative-to URL. That self-description
doesn't affect how it works. What you didn't do was:
po [[NSURL URLWithString:@"/login"
relativeToURL:self.sharedData.webServicesURL] absoluteString]
That would have shown the URL you expected.
