panic on `Downcast on stateless state` #195

Closed flukejones closed 1 month ago

flukejones commented 1 month ago

Happens as of commit 68dd4c37589a. Commits before this are fine.

Reproduce by opening cosmic-text then ctrl-o. The cosmic file dialogue shows briefly then panic.

Systemd is Fedora 40, no KDE or Gnome installed, only Cosmic.

This isn't the full log as it is very long and mostly doesn't look relevant.

Should be fixed now that libcosmic has been updated, can you test?

flukejones commented 1 month ago

Fixed now, thanks mate.
