Rhythmbox was working fine ubtil I tried to install a plugin https://github.com/srijan/StopAfterC...-for-Rhythmbox

But after I installed and tried to activate this, Rhythmbox crashed and would not restart.

I have tried removing the plugin & uninstalling and re-installing RB, but no luck.

This is my error.
Code:
paresh@desktop:~$ rhythmbox

(rhythmbox:9845): Gtk-WARNING **: A floating object was finalized. This means that someone
called g_object_unref() on an object that had only a floating
reference; the initial floating reference is not owned by anyone
and must be removed with g_object_ref_sink().

(rhythmbox:9845): GLib-GObject-WARNING **: invalid unclassed pointer in cast to `GtkWidget'

Can anyone help?
