Just saw this message when reading a mail-list mail, dialog reads:

An unknown error occurred while decrypting this message.

Alert reads:

`GPG error message: gpg: decrypt_message failed: Unexpected error

Please contact us, including the GPG error message, at`

Version info:

Mac OS X: 10.10.1 (14B25) MacGPG2: 2.0.26b2, 750b GPG Keychain: 1.2b3, 980b GPGServices: 1.10b2, 730b GPGPreferences: 1.5b2, 730b GPGMail: 2.5b4, 802b

The message in question is headed:

The massage showed a padlock for Encrypted, but the body at least is not encrypted at all, just attachments

    Ah, @ filtering was perhaps less than helpful here.

    The message ID is 549D9737.7020504 at sent to the mail list gnupg-devel at

    Hi Dave,

    thanks for your report. I can confirm your findings. We need to take a closer look for a more detailed analysis. Currently all we can say is: this message is structured rather odd.

    Attaching the mail in question as .eml file for further analysis.

    All the best,
