Correct string comparisson
Correct string comparisson

This worked fine locally where the string being compared was actually the same
(s1 is s2 == True), but failed when comparing strings that came from a
different source (e.g., an HTTP request).

Now that this is fixed the NM is happily working in real distributed
environments.
