[Kristian Rietveld <kristian src gnome org>]

commit e89782742df542ecbde582ccca6177a09103e5bb
Author: Kristian Rietveld <kris gtk org>
Date:   Sun May 22 18:26:37 2011 +0200

    Fix a couple of memleaks in the filter model tests
    
    (Not all of them yet, need to do the remainder on Linux since valgrind
    on Mac OS X is a bit too noisy).
