KDE5: minimwatch can not create sys tray icon

[tarnkappe]

The mentioned solution is for the unity-desktop. I cannot find something similar for KDE/plasma. Also the problem is different, because the icon already appears, but only the context menu does not. I think, if I really need it, I have to log into a different desktop or window manager (like icewm or maybe unity or gnome3). In most cases I need it for rescanning the library. But this can also be done via bubbleupnp or the minimserver web gui. So I am not completely lost.
