This morning I had a large upgrade from 6.18 to 6.20 (thanks for the work).However, I noticed several problems with directory management principally in dolphin but also digikam.
See bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1120915 I hope just a rebuild will fix it.For digikam it complains at start the photo directory is not there while it is but after the error it finds them correctly.
