Public bug reported:
I updated my OS to Ubuntu 19.04 recently. Upon doing so, I started to
see the following exception:
GStreamer version 1.12.2.0, gapless: False, replaygain: False
Unhandled Exception:

All the other solutions are years old don't seem to apply: mono is up to date,
this doesn't use DBus.Sharp, etc.
The program that is throwing the error is Banshee. I know the project is
long abandoned, but it was working up until the upgrade, so I am hoping
that I can either downgrade a package or do something to keep this
program zombified.
Does anyone know what I need to adjust to fix this?
