Please see the attached test program and the results output (combines  
stdout and stderr). The app uses plain gmime, no gpgme. In the output, the  
boundaries of the embedded multipart/mixed object have changed during the  
signing process, so I assume this is done by gmime. And I don't think  
calling g_mime_multipart_signed_sign() for an object should change it's  
contents, shouldn't it? Furthermore, the source file responsible for  
signing in balsa didn't change since 2 months, and it *did* work before  
the latest 2 or 3 gmime cvs upgrades.

Cheers, Albrecht.
