Linn Kazoo seems to be caching old album / playlist artwork

[schliden]

Even after a minimserver rescan, Kazoo shows old album / playlist artwork.

This is not artwork embedded in music files, but folder.jpg artwork in albums and playlist_name.jpg artwork.

This seems to happen when an artwork file is updated.

It affects the initial view in playlists, but when the specific playlist with the incorrect artwork is selected, the correct artwork is show in the playlist detail view.

Does anyone know how to force Kazoo to clear its artwork cache ?
