I am running 1.4.7 on Kubuntu Feisty. Amarok will not start when the system boots. I am left with a spinning disk (hourglass) in the system tray where the amarok icon should be. I kill amarokapp and run amarok again and it works fine. If I run amarokapp from the command line, I get the following feedback and it starts:

lingenfr@U100-UBUNTU:~$ amarokapp
