Hello!

I've recently started having issues with decrypting emails. thunderbird
was recently (september 8th, so 7 days ago) upgraded to 153.2.0. I
believe my issues started around the time of that upgrade.

In thunderbird's error console, I can see error messages when I try to
open an email that's pgp-encrypted. I'm attaching a screenshot of the
error console in case it can be useful for debugging. When that happens,
thunderbird does not mark the email as read.

Cheers!
