Probably similar to https://bugzilla.redhat.com/show_bug.cgi?id=2467252#c0.

Blame https://github.com/abrt/gnome-abrt/issues/381#issue-3138313547 and https://discussion.fedoraproject.org/t/cant-seem-to-change-the-fedora-version-of-a-bug-report-at-bugzilla-redhat-com/81664/4 for the OS replacement.

After switching to Mallitt, due to https://github.com/ValveSoftware/Proton/issues/9791#issuecomment-4461440176, it immediately SegV'd.
