Version: 2:
Severity: important

Dear Maintainer,

After the security upgrade to Thunderbird version 52.2.1 Enigmail did not work
anymore. I've tried now Enigmail version 2: but it has the same
problem.  Because I could not install this version of Enigmail using apt, I've
downloaded it from here:
And installed it with "dpkg -i".

When I read an encrypted message in Thunderbird, I get this warning:

This is a system setup or configuration error that prevents Enigmail from
working properly and cannot be fixed automatically.

After this, the message is decrypted.

But when I sent a message to somebody with a PGP key in my keyring, the message
is normally encrypted. But not now, and I do not get a warning about that.

With Thunderbird 45 I did not have these problems.

With regards,
Paul van der Vlis
