#606 Enigmail munges display of messages with S/MIME signature
If Enigmail is enabled, it's munging some of my mail so that it shows the MIME structure. Disabling Enigmail makes the problem go away. See attached screenshots. Let me know what extra info you need. This is stable Enigmail on stable Thunderbird.
I think it may be relevant that the message has an S/MIME signature.

That's a multipart/mixed message containing an s/mime signed message. I assume that v1.9.1 did not have that bug?
Despite the name of the page, https://www.enigmail.net/index.php/en/download-old-versions doesn't seem to make it easy to download old versions, just alternative builds of the latest version. But by guessing at the URL, I have a 1.9.1.
I rolled back to that version, and it indeed seems that it wasn't a problem there.

As Enigmail and S/MIME share the handler fort Content-Type "multipart/signed", Enigmail has a switch point for handling S/MIME and PGP/MIME.
The problem turns out to be that Enigmail would only recognize protocol="application/pkcs7-signature", but not the used protocol="application/x-pkcs7-signature".
Fixed on master and on release branch.
Is there a proposed release date for 1.9.3?
Soon ;-) I'm actually waiting for input on bug 613
In the meantime, you can download the latest nightly build - it's still almost identical to the 1.9.x branch.

#613I'm still seeing a problem with messages showing up as blank in 1.9.3. Here's an example.

The message displays fine for me if I copy the .eml file to a local folder. Do you receive/view the message on a NNTP newsgroup?
Yes, exactly. Sorry not to mention that.
Gerv
After so many years, the mailnews code still surpises me from time to time. The NNTP implementation is just slightly different than POP and IMAP, which made my code fail :-(
Actually, the behavior (S/Mime signed e-mails are shown empty, protocol="application/pkcs7-signature") still occurs in the case that one installs enigmail but has not yet installed GnuPG. I experienced this yesterday with current enigmail (and 1.9.4 and 1.9.3), thunderbird 45.2.0 on Mac. After installing GnuPG, i can see signed S/Mime e-mails again without problems.
Indeed yes. Fixed on master - thanks.
Patrick: I'm still seeing problems with message display of newsgroup messages with an application/pkcs7-signature. Should I reopen this bug or file a new one?
Please file a new bug. I think the cause is completely different than this one.
Is this still fixed? I am unable to view messages in my sent folder which are signed with S/MIME. Disabling Enigmail allows them to be properly viewed. Not sure if this bug sprung back to life or whether it's something new that I should submit a new bug for.
Please submit a new bug and attach a sample message. Thanks.
