--- Comment #13 from Sandro Knauß <sknauss at kde.org> ---
I can confirm it, but it is not reproducible with every gpg key, what is quite
strange.

What I checked is to create a draft with X-Face enabled. For one gnupg key the
signatures keep fine. When I select another key, the signature is broken with
the same X-Face. (I actually modified the identity and change the gnupg key and
the matching email address).

At least, if those mails get send, the signautre would get broken in any case,
as the X-Face line is too long for most mail servers, so they would break the
line and this will break the signature in always.

@David: can you check, if you get proper signatures, if you disable the picture
(X-Face)? (Picture tab of the Identity).
