I didn't reviewed the full source code but something that hit my eyes is
your re-parenting code. 

You should not take a GtkWidget out of its container without holding a
reference to it, as it can be destroyed when you do that.

The steps for re-parenting a widget should be:

g_object_ref()
gtk_container_remove
gtk_container_add
g_object_unref()

But better to try gtk_widget_reparent ().
