Hi,
console output is:

<unknown program name>(2185)/: Communication problem with  "amarok" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.ServiceUnknown" : " "The name org.kde.amarok was not provided by any .service files" " 

Any workaround?
deleting /var/tmp/kdecache-.../ksycoca4 did not help
