System.ArgumentException: Specified value has invalid Control characters

[Bill]

I'm getting an error sporadically for this line:
var response = openIdRelyingParty.GetResponse();

Any help would be really appreciated.

Error details:

The only cause for this I can find is invalid incoming HTTP headers.  I've made a change based on your exception so that in future releases these errors are silently ignored (emitting a warning to the log) so it doesn't crash your web site.

If you can capture and forward the HTTP headers that reproduce this problem, I'd love to see it.
