digikam hangs on panorama completion

Can anyone else confirm they see digikam hang on completing a panorama?

The actual panorama appears to be complete in

/tmp/digiKam-panorama-tmp-xxxxx/

But the panorama tool and digikam appear to be hung and their windows don’t refresh.

There isn’t anything in logged in .local/share/sddm/xorg-session.log

The problem was due to digikam and related items being installed from the graphics repo. I thought I had reverted to the stock repo, but it turns out I hadn’t. Either that, or I needed to reboot to kick out processes holding onto the old libraries. After making sure I had the right versions installed, and after a reboot, everything is fine.
