In current Rawhide (e.g. Fedora-Rawhide-20190625.n.0), Calendar reliably crashes on startup. Very easy to reproduce: boot a current Rawhide Workstation live (e.g. https://kojipkgs.fedoraproject.org/compose/rawhide/Fedora-Rawhide-20190625.n.0/compose/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-Rawhide-20190625.n.0.iso ), run Calendar. It may start up very briefly, but it'll then crash. Also happens from an installed system. Backtrace attached. Proposing as a Final blocker, per "All applications that can be launched using the standard graphical mechanism of a release-blocking desktop after a default installation of that desktop must start successfully and withstand a basic functionality test" - https://fedoraproject.org/wiki/Fedora_30_Final_Release_Criteria#Default_application_functionality

Thanks for that, but mcatanzaro had already done it. Sorry, I forgot to update this. https://koji.fedoraproject.org/koji/taskinfo?taskID=36108696 should fix this, unless we're hitting the mysterious https://gitlab.gnome.org/GNOME/gnome-calendar/issues/417 which no-one's managed to fix yet.
Looks like this is fixed, test now passes. #417 is still a thing, but we can track that upstream.
