[Dodji Seketeli <dodji src gnome org>]

commit 6e8cb6bc84331b0eeb8462389af209916a3e711e
Author: Dodji Seketeli <dodji redhat com>
Date:   Sat May 30 21:49:28 2009 +0200

    New nmv_abort_on_throw environment variable
    
    	* src/common/nmv-exception.h:
    	When nmv_abort_on_throw is set, abort on throw.
    	This is useful to debug some nasty issues.
