This small hack will modify the nautilus breadcrumbs of your current theme.
Breadcrumbs will look similar to victory theme's ones, without the need of using victory theme.
In the screenshots you can see hacked breadcrumbs with three different themes: rdiance-flat http://gnome-look.org/content/show.php/radiance-flat?content=127398, elementary and ambiance.
Should work with any theme, but tested only on ubuntu 10.04 with nautilus elementary.
place the downloaded file in your home folder, then extract it from the terminal:
tar xvzf *-victory-breadcrumbs-0.2.tar.gz
then restart nautilus:
rm -fr ~/.themes/nautilus
