Your code sample cuts off before (I think) it gets to the last point of contact
with your code in the crash. We don't see any use of the keys and values
arrays. Could you offer a complete listing, and tell us where in the method the
crash occurs? Give us the full stack trace, which might provide a clue of what
went wrong.
Also, have you verified the types of url, displayName, and browser? If your
"url" is an NSURL/CFURLRef, that's likely your problem; the ternary operator
shows you expect the value to be a CFString.
