I enabled Replay Gain in Rhythmbox and the program closed and now I cannot open the program at all. If I run it from terminal I am met with:

/usr/lib/python2.7/dist-packages/gobject/ Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
  import gobject._gobject
TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
ERROR:/build/buildd/pygobject-3.0.0/gi/_gobject/pygobject.c:929:pygobject_new_full: assertion failed: (tp != NULL)

If I uninstall the "plugins for rhythmbox music player" package, Rhythmbox opens, obviously missing all of the plugins.

I am assuming there's a config file or folder somewhere enabling all of the plugins I selected when I re-install the "plugins for rhythmbox music player" package because when I re-install the package, the issue occurs again.

Any ideas?

Ok This was a tricky one. It turns out there was no issue with the Replay Gain plugin but rather the Magnatune plugin. What I needed to do was disable it being loaded when opening Rhythmbox by doing this:

1) Alt + F2 and entering dconf-editor 2) Navigating to org > gnome > rhythmbox > plugins 3) Removed the magnatune entry from "active-plugins" 4) (Don't know if this helped) navigated further within the Rhythmbox plugins menu to magnatune > source and deselected "show-browser"

Run this in terminal:

sudo rm -rf /usr/share/rhythmbox/plugins/magnatune/
sudo rm -rf /usr/lib/rhythmbox/plugins/magnatune/

And try to launch Rhythmbox again!
