Nope, I did not manage to figure out. Hoping the next release of 4.5 will be able to resolve it.

Hi, I bumped into your question. It seems that there is a call with a base64 encoding. This encoding allows only 1000 characters. If your string is bigger than that you get the 'System.FormatException: Invalid length for a Base-64 char array. at System.Convert.FromBase64String(String s)'.
I hope this will point you in a direction.
