Setting layout from command line doesn't work

$ mate-tweak --get-layout
Window Manager is: marco
System installed layouts: 
['fedora', 'default', 'opensuse']
Current layout: witek-tweak

$ mate-tweak --layout witek-tweak

Same when trying to use fedora or default

I am on Debian testing, with pretty standard layout, with just added few launchers, cpu frequency and system monitor applets.

mate-tweak 22.04.8-1

Actually it might be because of mate-media package was removed from Debian. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=971783

Still, it would be good to fall more gracefully.

The bug mentioned doesn't speak about removal (yet), and it's hasn't. However, MATE changed the name of the "applet" (that is not really one, it's a status icon) to mate-volume-control-status-icon, so you'll have to adjust in your custom profile.

This said indeed maybe mate-tweak could either help the transition, or fail a little more gracefully (maybe simply explaining what's wrong instead of a plain backtrace).
