According to previous posts and result of tests, it seems that the  
problem is with GPGMail signing with OpenPGP/MIME *and* SHA224.

OpenPGP/MIME is set by default when sending a message with an  
attachment, or a multi-part message (e.g. HTML format).

You'd better check your gpg.conf, and:
disable the option digest-algo SHA224

and use instead:
digest-algo SHA256

Best regards,
Charly
