I think there might have been some change in rpm bindings lately which change the returned objects. Here are the versions of used libraries:

Yes, this is the API change in rpm Python bindings. Thanks for the report, I'll try to fix this. However, the rawhide docker image has not yet been updated, so the CI is useless here. Let me try to stick a dnf update call somewhere there.

Working on this in #87

Huh, I just noticed, we're not supposed to be running Taskotron tasks on Rawhide, but we clearly are. I'll find out what went wrong, and the crashes will hopefully go away once we run on F30 again.

[hroncok]

Either way we test on rawhide as well and the failure just got reproduced on the CI. A fix is trivial.
