Could you provide the core dump and also ideally contents of the /var/lib/dnf/ directory so we can reproduce the problem?

dnf started to work after deleting /var/lib/dnf directory.
I got essentially same dump when trying to do 'dnf check-update' or 'dnf update' etc. Deleting /var/lib/dnf directory solved the problem for me too. I got this problem with f29 beta version of dnf and then I upgraded it by hand from koji without any progress and current versions are: dnf-plugins-core-3.0.4-1.fc29.noarch python3-dnf-plugins-extras-common-3.0.1-1.fc29.noarch python3-dnf-plugin-leaves-3.0.4-1.fc29.noarch python3-dnf-plugin-versionlock-3.0.4-1.fc29.noarch dnfdragora-updater-1.0.1-13.git20180108.b0e8a66.fc29.noarch dnf-3.6.1-1.fc29.noarch etckeeper-dnf-1.18.8-1.fc29.noarch libdnf-debuginfo-0.20.0-1.fc29.x86_64 dnf-automatic-3.6.1-1.fc29.noarch dnf-utils-3.0.4-1.fc29.noarch dnfdaemon-0.3.19-4.fc29.noarch python3-dnf-3.6.1-1.fc29.noarch python3-dnf-plugins-core-3.0.4-1.fc29.noarch python3-dnfdaemon-0.3.19-4.fc29.noarch python3-dnf-plugin-rpmconf-3.0.1-1.fc29.noarch libdnf-0.20.0-1.fc29.x86_64 dnfdragora-1.0.1-13.git20180108.b0e8a66.fc29.noarch python3-libdnf-0.20.0-1.fc29.x86_64 python3-dnf-plugin-local-3.0.4-1.fc29.noarch libdnf-debugsource-0.20.0-1.fc29.x86_64 python3-dnf-plugin-system-upgrade-3.0.1-1.fc29.noarch dnfdaemon-selinux-0.3.19-4.fc29.noarch dnf-data-3.6.1-1.fc29.noarch
Just ran into this too after a a dnf system-upgrade to f29. Deleting /var/lib/dnf did the trick, before that all dnf operations failed with the above stacktrace. $ rpm -qa | grep dnf libdnf-0.20.0-1.fc29.x86_64 python3-dnf-plugins-core-3.0.4-1.fc29.noarch python2-dnf-plugins-extras-common-3.0.2-1.fc29.noarch dnf-yum-4.0.3.6.1-2.fc29.noarch dnf-3.6.1-2.fc29.noarch python3-dnf-plugins-extras-common-3.0.2-1.fc29.noarch python3-dnf-plugin-system-upgrade-3.0.2-1.fc29.noarch python3-libdnf-0.20.0-1.fc29.x86_64 python2-dnf-3.6.1-2.fc29.noarch python2-libdnf-0.20.0-1.fc29.x86_64 dnf-automatic-3.6.1-2.fc29.noarch dnf-data-3.6.1-2.fc29.noarch dnf-plugins-core-3.0.4-1.fc29.noarch python3-dnf-3.6.1-2.fc29.noarch I still have the /var/lib/dnf directory for now, let me know if you need it for debugging.
Seems worth considering as a Final blocker, we really do not want people who upgrade to F29 hitting this.

I agree with comments 6,7,8.
Marking accepted, then.
dmach, tomasz torcz suggests 1600917 is probably the same bug as this; can you check and close one as a dupe of the other (doesn't really matter which way around, it's up to you) if you agree? Thanks!
Yes, it's a duplicate. I've created a fix that avoids the crash: https://github.com/rpm-software-management/libdnf/pull/614 We'll need more time for a proper patch, but that can be done after F29 release.
