Version: (using Devel) Installed from: Compiled sources Issuing a collection rescan doesn't clear the images table, which means that albums are then showed with incorrect artwork as album ids have changed whilst image ids which reference them have not. A workaround would be to delete all from the images table, but this would cause us to lose information about which images have been unset, or custom images which are used.
this is probably a dupe of https://bugs.kde.org/show_bug.cgi?id=178973
