If Sending a PGP signed message, and something like network or server outage happens (or I cancel the sending), the message text is corrupted. Notably, lines starting with > are REMOVED. That's bad, since lines starting with > are quotes. (Sometimes, parts of the quoted message are kept)
Turning PGP signing OFF, I can Send|Cancel all day and the message body is preserved.
Bug occurs in Thunderbird 17.0.5 on Linux Mint 12 with
gpgp 1.4.11/Enigmail 1.6
Thunderbird 24.0 on Linux mint 15 with
gpg 1.4.12+/Enigmail 1.6
Trying to attach a video showing the strange behaviour.
