Comment 1 for bug 1732807

Same thing on 18.04. Soundconverter version 3.0.0.

Found this in debug output:
"id3mux" gstreamer element not found, disabling MP3 tags output.

The id3mux element is found in gst-plugins-bad. Should probably make gstreamer1.0-plugins-bad a dependency on bionic. Installing the package manually fixes the problem.
