Apparently Muon discover uses the monochrome systray icon instead of the official Amarok logo. Please use the Amarok logo as provided by Amarok instead
Might be that the plasma icon cache interfers with icon loading.
Plasma Components always use the system tray variant. I'll see if I can fix it, I'm unsure.
Well, when you search in the list below you get the correct blue log, only when you click on the information the top shows the monochrome one. Believe me, as a showcase for a new user we (the Amarok Team) really would want to see the correct logo there.
Git commit e582c6ae489916640a38d44443489b68ae5fd9bd by Aleix Pol. Committed on 28/02/2014 at 14:28. Pushed by apol into branch '2.2'. Use QIconItem instead of PlasmaCore.IconItem This way Plasma won't get the system tray icons but the system ones, which is the ones we're looking for.
