I've gotten through installing with no errors, but when I run switcher-control I get this error:
Traceback (most recent call last):
File "/usr/local/share/switcher/gtk_switcher/__main__.py", line 26, in new_window
AtemWindow(self, self.args)
File "/usr/local/share/switcher/gtk_switcher/atemwindow.py", line 111, in __init__
builder.add_from_resource('/nl/brixit/switcher/ui/mixer.glade')
gi.repository.GLib.Error: gtk-builder-error-quark: .:3002:1 Invalid object type 'HdyStatusPage' (6)
Looking at mixer.glade file I don't see anything obvious to me what is wrong, any ideas what I did wrong?
