firefox enigmail has a problem wiht gpg
 

for some specific emails, i get this message when it is trying to confirm the signed message

gpg command line and output:,/usr/bin/gpg --charset utf8 --batch --no-tty --status-fd 2 -d,gpg: unexpected armor: -----BEGIN PGP SIGNED MESSAGE-----\n,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 3F skipped,gpg: invalid radix64 character 2C skipped,gpg: invalid radix64 character 2D skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2C skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 3A skipped,gpg: invalid radix64 character 27 skipped,...,gpg: CRC error; 11C8E5 - A58C30,gpg: packet(2) with unknown version 45,


does anyone know what that is about? or how i can make it work?
