kf5 5.25 in testing, systray elements not working

[Francesco De Vita <fradev@inventati.org>]

Hello

On August 31st, kf5 packages in Testing were upgraded to version 5.25. After 
this update the elements of the systray (audio volume, networks, printers, 
battery, notifications,...) do not work, their icons are missing and instead 
there are blank spaces where these elements should appear.

If I create a new panel, it shows the missing elements but after few seconds 
plasma-shell (I suppose) crashes and the systray elements disappear. However, 
the same elements work if used as plasmoids outside of the systray.

Is it an already known issue?

Ciao
Francesco
