firefox works but issues error output

[sudodus]

Running an installed Lubuntu Utopic 32-bit system

Starting Firefox from a terminal window there is output (to the terminal window) which says 'error' not 'warning', but Firefox runs anyway:

Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkRange::activate-slider' of type `gboolean' from rc file value "((GString*) 0xad9a75a0)" of type `GString'
