No, we won't release random git snapshots... ;-)

But can you be a bit more specific please?

What commit is supposed to fix it? I don't see a recent one that would change
anything in this regard.

And kwave definitely shows up in Multimedia here when using Plasma.
Which desktop are you using? The problem may lie there.

And actually your problem may be that we override the categories via
%suse_update_desktop_file -r org.kde.%{name} Qt KDE AudioVideoEditing
