[Pkg-mozext-maintainers] Bug#782669: enigmail: Can't decrypt messages vom "OpenPGP für Windows Phone"

[derMaria]

Package: enigmail
Version: 2:1.7.2-3
Severity: important

Dear Maintainer,

whenever I get a mail from someone who encrypted the Message with "OpenPGP für
Windows Phone" from Christoph Müller <http://www.windowsphone.com/de-
de/store/app/openpgp-f%C3%BCr-windows-phone/0a1906e2-eb48-4cdb-bbab-
30ea308b9065> I cannot decrypt the message. That program seems to encrypt only
attached files, not the mail body. When I click "decrypt and open file" in
Icedove 31.6.0 it creates a 0 Byte textfile and opens it in my texteditor.

If I try to decrypt the file with gpg I get the following output:

me at myComputer:/tmp$ gpg --decrypt --output decrypted-text.txt message.txt.asc

You need a Passphrase, to decrypt the secret key.
User: "My Name <myname at provider.de>"
4096-Bit RSA Schlüssel, ID xxxxxxxx, created [date]

gpg: decrypted with 2048-Bit RSA key, ID iiiiiiii, created [date]
      "Friends Name <friendsname at provider.com>"
gpg: decrypted with 2048-Bit RSA key, ID rrrrrrrr, created [date]
      "Friends Name <friendsname at provider.com>"
gpg: decrypted with 4096-Bit RSA key, ID xxxxxxxx, created [date]
      "My Name <myname at provider.de>"
gpg: uncompressing failed: Unknown Komprimierverfahren [compression method?!]


My friend said it is "Cast5 with Sha1 without compression"


   * What outcome did you expect instead?
If the problem is lying in incorrect encrypted files I expect a proper error
message like this in GPG. But in general I expect it to be able to understand
the Komprimierverfahren [compression method?!]

Thanx alot for your great work!
