Running remote-viewer will throw some warnings:
(remote-viewer:546): Gtk-CRITICAL **: gtk_application_get_app_menu:
assertion 'GTK_IS_APPLICATION (application)' failed
(remote-viewer:546): Gtk-CRITICAL **: gtk_application_get_menubar:
assertion 'GTK_IS_APPLICATION (application)' failed
This does not happen with virt-viewer. I attached the gdb backtrace to
this mail.

Again, this call to _hold() is only necessary for remote-viewer,
otherwise the application will quit the mainloop before showing the main
window. This is not necessary for virt-viewer, and I tried to track the
reason, without success. Maybe someone can help here.

In this case we set the handler to NULL to avoid some warnings that will
be thrown by the default handler. We could have defined a function which
did nothing, as all command line options were already handled in
local_command_line().
