YouTube : Unhandled Web Exception

[Carlito]

I was downloading a video through the YouTube plugin which resulted in a crash of gbpvr.
I got the famous "Send this to microsoft" pop-up (no thanks, I don't remember signing up to be a beta tester) but in the background gbpvr was still running AND the video still downloaded and played fine.
Looking through the logs I found this:
FATAL UNHANDLED EXCEPTION:: System.Net.WebException: The remote server returned an error: (500) Internal Server Error.
at System.Net.HttpWebRequest.GetResponse()
at GBPVR.xa80c4fa0df664a15.xcba1f05fb5a46d5f()
at System.Threading.ThreadHelper.ThreadStart_Context(Object state)
at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
at System.Threading.ThreadHelper.ThreadStart()

Any idea why/how it got a 500 error yet still downloaded and played the video?
