I'm resending mail I sent in the past week (from a different account)
it appears scam is not sending remote mail.

That is exactly what is happening. gtk_container_add calls
gtk_widget_set_parent which is where widgets (objects) get
referenced. But the box container_add functions also calls
gtk_widget_set_parent, referencing the widget again. I've gone through
gtk and fixed places where this occurs. I've also put code into
gtk_widget_set_parent so that it will warn you if you set the parent
of a widget to its current value (which is what happened in this case)
or if you call gtk_widget_set_parent when the widgets parent field is
non-NULL. (ie. It already has a parent).
A patch to do all this follows. (gzipped and uuencoded)
