g-s-r can't record to mp3 format

[Paride Legovini]

When mp3 is chosen as the preferred format, g-s-r fails to record audio. Pressing the "record" button puts it in "record mode", but no audio is actually recorder. I have installed libgstreamer-plugins-{good,bad,ugly}.

Console output is the following:

Gjs-Message: 15:40:01.627: JS LOG: Sound Recorder (org.gnome.SoundRecorder)
Gjs-Message: 15:40:01.627: JS LOG: Version: 43.beta

[here I press the record button]
