Project demoing bug

Try to fetch this url:

http://cdn4.libsyn.com/nerdist/Number_14_-_Stan_Lee.mp3?nvb=20100504045911&amp

using WebRequest. It fails with this error and this response URL:

- The remote server returned an error: (404) Not Found.
http://cdn3.libsyn.com/cdn4.libsyn.com/nerdist/Number_14_-_Stan_Lee.mp3?nvb=20100515023123&nva=20100516024123&t=084f35bf52b35aa87a486

But it should resolve to:

http://cdn4.libsyn.com/nerdist/Number_14_-_Stan_Lee.mp3?nvb=20100515023937&nva=20100516024937&t=0e16d84c4fb7cc40a29c1

It seems that it is concatenating URLs together incorrectly. 

Here is a log of the redirect chain:
