gdl test-dock warnings (assertions etc.)

Hi

what to do about these warnings:
---
(lt-test-dock:8608): GLib-GObject-CRITICAL **: g_object_unref: assertion
`G_IS_OBJECT (object)' failed

(lt-test-dock:8608): Gdl-CRITICAL **: gdl_dock_object_freeze: assertion
`object != NULL' failed

(lt-test-dock:8608): Gdl-CRITICAL **: gdl_dock_object_bind: assertion
`object != NULL && master != NULL' failed

(lt-test-dock:8608): Gtk-CRITICAL **: gtk_container_add: assertion
`GTK_IS_CONTAINER (container)' failed

(lt-test-dock:8608): Gtk-CRITICAL **: gtk_container_add: assertion
`GTK_IS_CONTAINER (container)' failed

(lt-test-dock:8608): Gtk-CRITICAL **: gtk_container_add: assertion
`GTK_IS_WIDGET (widget)' failed

(lt-test-dock:8608): Gtk-CRITICAL **: gtk_widget_show: assertion
`GTK_IS_WIDGET (widget)' failed

(lt-test-dock:8608): Gdl-CRITICAL **: gdl_dock_object_thaw: assertion
`object != NULL' failed
---

On a gentoo computer I don't get these errors, but on debian I do.

They seem "CRITICAL", and arrives in our own code and in the test-dock
example shipped with gdl.
