gnome print dialog crash

Hi,

i'm in the process of making epiphany support libgnomeprint[ui], but
i've run into a problem: Whenever a GnomePrintDialog is destroyed, the
program segfaults. This also happens for the example programs in the
examples/ directory of libgnomeprintui (example_06, 08, 10, 11, with the
unexpected exception of 09).

Is this a known problem of libgnomeprintui or a problem on my side?
(I've had one other epiphany developer try this, and he also reported
the same problem.)

On the console, the following is shown when this happens:

(lt-example_10:3727): GLib-GObject-CRITICAL **: file gobject.c: line
1337 (g_object_unref): assertion `G_IS_OBJECT (object)' failed

(lt-example_10:3727): GLib-GObject-CRITICAL **: file gobject.c: line
1338 (g_object_unref): assertion `object->ref_count > 0' failed

(lt-example_10:3727): GLib-GObject-CRITICAL **: file gobject.c: line
1337 (g_object_unref): assertion `G_IS_OBJECT (object)' failed

(lt-example_10:3727): GLib-GObject-CRITICAL **: file gobject.c: line
1338 (g_object_unref): assertion `object->ref_count > 0' failed

I can provide a backtrace if needed.

Any thought?

Thanks,
	Christian
