When making any D-Bus call through the GDBus' proxy wrapper with an invalid D-Bus object path, gnome-shell hangs. Supposedly FdoApplicationProxy constructor should validate the passed D-Bus object path and throw an error if the path is invalid. Since it does not do that, we work it around by making sure that the deduced D-Bus object path is valid or throw an exception if the path is not. https://bugzilla.gnome.org/show_bug.cgi?id=787902
