Description Ben Cotton 2026-07-22 21:51:22 UTC 
My F45 builds of Cherrytree in Copr fail (F43-44 build successfully).

Excerpts from https://download.copr.fedorainfracloud.org/results/bcotton/cherrytree/fedora-rawhide-x86_64/10759266-cherrytree-future/builder-live.log.gz

Cherrytree upstream has confirmed in https://github.com/giuspen/cherrytree/issues/2889 that it is not related to Cherrytree's use of the library

Reproducible: Always
Comment 1 wojnilowicz 2026-07-24 15:24:50 UTC 
Did you see https://bugzilla.redhat.com/show_bug.cgi?id=2502740 and ruled it out as a reason?
Comment 2 Ben Cotton 2026-07-24 17:15:09 UTC 
No. I was originally about to file it against a different package and did my duplicate search there. My apologies!
