It looks like the "Version" header is too long and is wrapping onto a
2nd line.  The 2nd line is not a valid header, and is confusing gpg.
Most likely, this is caused by the email client on the sending side
wrapping the text.  (Although maybe some receiving clients re-wrap
text, I'm not aware of any.)

Can you provide information on the client(s) in use?
