I have no solution for your problem, but I have a similar problem - 
in my case it is a mail to the debian-security-announce mailinglist,
and the mail does have a ü (non-ascii) character in the body - I don't
see anything like that in your mail though. To me it looks like all
mails that got non-ascii characters in the body fails signature
validation.

Mail attached, but also available online:
https://lists.debian.org/debian-security-announce/2013/msg00055.html

A gpg --verify does report a good signature, but Claws doesn't.
Is it related?
