With the help of DaveBlake an issue when upgrading from Jarvis to Krypton was found. Basically it takes a lot of time (up to eight minutes) to open the playlists screen in the music section if the kodi cache was not deleted before running Krypton. I guess not many users will do so, so maybe another solution can be found.
