Running ArchLinux, fully updated and Digikam always ran perfectly well. Suddenly, all thumbnails have disappeared from the main screen - thumbnails are still available in calendar view and, from there open neatly in ShowFoto for editing. Checked whether any filters but none applied. Refreshed albums to no effect. Even deleted and rebuilt DB, finally entirely removed and reinstalled Digikam.
What am I missing? Only thing I can think of would be a small edit I made to a file in /usr/share/lensfun to one of the XML files but I cannot imagine that to be a source of trouble.
Ran digikam from the konsole and I can see nothing untowards in the output there either. Ideas are appreciated…
