Traceback: GNOME Audio Profile output can be selected if no profiles are available

[Michael Schwendt]

https://bugzilla.redhat.com/910613

If no audio profiles are found via GConf, in gstreamer.py audio_profiles_list is empty. In ui.py set_widget_initial_values(), other encoders get deleted (del model[i]) if not available, but not "gst-profile". That one is missing a special check to delete it if no profiles are available.

As I don't grok the enabling/disabling of encoders yet (in particular, the relationship of the encoder_present and available_elements values), I've opted for the short'n'sweet brute-force workaround that disables the gst-profile output, if audio_profiles_list is empty.
