Installing hildon-desktop-python-loader made no difference.

I was able to get it [the widget] started from the command line by moving "import gobject" to the beginning, creating an object of type UssdWidgetPlugin, showing_all() and doing a gtk.main().

I'll stick with the pad, as having to run the widget from X Terminal isn't fun.

One suggestion, however; emit the "settings-changed" signal if the button's label is "Configure me" so that it can quickly be configured instead of trying to "dial" out an empty number.

Thanks, pycage and KiberGus.
