Batch mode not working

[Christian M. Schmid]

When starting soundconverter in batch mode using the the option -b, which according to the soundconverter docs should "Convert in batch mode, from command line, without a graphical user interface. You can use this from, say, shell scripts.", soundconverter fails.

E.g., the command

----
soundconverter -b -m "audio/mpeg" -s ".mp3" test.flac
----

on Ubuntu 12.04.2 leads to

----
SoundConverter 1.5.4
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display
  warnings.warn(str(e), _gtk.Warning)
  using Gstreamer version: 0.10.36
  using gio
        'faac' gstreamer element not found, disabling AAC.

(soundconverter:10037): GConf-WARNING **: Client failed to connect to the D-BUS daemon:

the error is reproducable with both
- 12.04.2 LTS with soundconverter 1.40-1ubuntu1
- 12.10 with soundconverter 2.0.1-1 (the error message looked a little bit different there, but the problem source is essentially the same)
