I can see the spotify plugin is involved, even though i have not enabled it.

[muesli]

The spotify plugin is involved because we try to load the Spotify charts from our server here. The crash isn't fixed yet, but I've finally managed to migrate the service to our new server, so the crash shouldn't be triggered anymore.
