No worries.

You're right - the `type.FullName` can be `null` (see http://msdn.microsoft.com/en-us/library/system.type.fullname%28v=vs.110%29.aspx for the details) so we've been using this fallback to `type.Name` to give the most detailed description in a given situation.

I'm afraid this is the best we've got, short of extracting this into an extension method.
