#245 Signature validation fails

[Julian Stecklina]

Signature verification of the attached email fails, even though other clients (tested with Emacs/Gnus) validate the signature just fine.

Steps to reproduce:

1. gpg --recv-key 7A560AB6
2. Open the attached mail in Thunderbird.

Same issue exists with gnupg 1.4.16. I am running Fedora 20 on amd64.

Same as bug 209 ([bugs:#209]); the mail verifies successfully with the current nightlies.
