Comment 1 mnd999 2022-02-11 09:23:04 UTC

I'm not sure if any of this is relevant:

* Pretty sure this was working before I upgraded the CPU from a 6700k to an Epyc.
* My GPG key is stored on a Yubikey

Comment 2 Hauke 2022-02-11 14:41:14 UTC

Can confirm:

1. Create a new mail with an attached GPG key
2. Enter anything in the "To" field

When starting from the terminal, the log output of KMail looks pretty much the same as describes in #449898 comment 2 (https://bugs.kde.org/show_bug.cgi?id=449898#c2)
