However, despite promises that all these extensions will not be loaded, 
I happily use some of them: gnome-shell-extension-freon, 
gnome-shell-extension-weather, vertical-workspaces from 
gnome-shell-extensions-extra, gnome-shell-pomodoro, removable drive menu 
from gnome-shell-extensions, and workplace indicator from 
gnome-shell-extensions. These messages are misleading at least (and they 
might be indicative of further problems).
