gtk-demo : GLib-GObject-WARNING **: Two different plugins tried to register 'BasicEngineFc'

[Gowri Kandasamy <sharmikg gmail com>]

I Get the following message when I runt gtk-demo. The demo comes up.
But When I move the focus to the main frame , the program crashes. The
following is the trace from GDB. Does any one has seen this problem .
I see this with GTK 2.4 & GTK 2.6.

gtk-demo:17231): GLib-GObject-WARNING **: Two different plugins tried
to register 'BasicEngineFc'.

(gtk-demo:17231): GLib-GObject-CRITICAL **: file gobject.c: line 819:
