In-place decryption no longer working?

[Sven Künzler]

Hello,
since the latest update of my Thunderbird-Addon the in-place decryption of messages is no longer working. I get prompted for the pass phrase but nothing else happens.
I can decrypt-to-folder just fine. But then I have to decrypted messages lying in a folder which I do not want.
Is there any way to get the old behavior back?

Thanks,
Sven

Is there no red error message above the message pane (below the message list)?

[Sven Künzler]

Hi,

no there is no error message. Other than being the German localization, my Thunderbird should be pretty much a vanilla setup. Enigmail + Lightning are the only addons installed.

Wait a minute, something is not right here...

When I open an encrypted message in the message preview pane and scroll down to the end, Thunderbird shows the source of the next message in my inbox.
For example:

{...]
QlbqyeTPT4FAAYppFPcniqBOUiOPud+olCxeZVT9L1Cz1umMw+dghiYX7Obb4gVW
RLH0Q1Q5y3NM0tKyaHhoHpX1OvHvuNAS

-----END PGP MESSAGE-----

X-Mozilla-Status: 0001
X-Mozilla-Status2: 00000000
Return-Path: noreply@sourceforge.net
{...]

The encrypted message and the SourceForge password recovery are completely unrelated other than being next to each other in my inbox.

This happens with encrypted mails as soon as I decrypt them to another folder. These messages stay that way even if I restart Thunderbird and/or deactivate Enigmail.

Then you might want to repair the foler. Context menu on the folder > Properties > button Repair folder.

Well yes that solves that problem with the broken messages. The in-place decrypt still does not work, though.

Is there anything further I could investigate?

Thanks,
Sven

I'll try to investigate directly, sent PM to Sven.
