Comment 1 Sławek 2022-09-18 17:56:25 UTC

I just found out that problem is fixed when I downgraded libs:

gpgme-1.17.0-4.fc36.x86_64 to gpgme-1.15.1-6.fc36.x86_64
gpgme-devel-1.17.0-4.fc36.x86_64 to gpgme-devel-1.15.1-6.fc36.x86_64
gpgmepp-1.17.0-4.fc36.x86_64  to gpgmepp-1.15.1-6.fc36.x86_64
gpgmepp-devel-1.17.0-4.fc36.x86_64 to qgpgme-devel-1.15.1-6.fc36.x86_64
python3-gpg-1.17.0-4.fc36.x86_64 to python3-gpg-1.15.1-6.fc36.x86_64
qgpgme-1.17.0-4.fc36.x86_64 to qgpgme-1.15.1-6.fc36.x86_64
gpgmepp-devel-1.17.0-4.fc36.x86_64 to gpgmepp-devel-1.15.1-6.fc36.x86_64

So bug is probably in one of those packages in 1.17 version

kmail (5.20.1 (22.04.1)) using Qt 5.15.6

Every time I try to type anything in the To: field in the new mail window, the application crashes.
Same happens when trying to reply to someone as well.

Here is the same crash as before but (hopefully) with debug data

Comment 4 Ingo Klöcker 2022-10-01 16:55:43 UTC

qgpgme 1.17.0 was binary incompatible. Please file a bug with Fedora that they need to skip 1.17.0 and use at least 1.17.1. See https://dev.gnupg.org/T5872.

yup, can confirm `sudo dnf downgrade qgpgme` solves the issue.
