[Sidefx-houdini-list] Disable Gravitational Lensing

OK. Perhaps I was being a little too cutesy with my previous post...
but there was a serious side to it.
I'm getting a strange artifact when rendering with DOF. The blurred
area around foreground elements is warping the background, (hence the
"gravitational lensing" reference).
If you step through the 10 frames here...
http://www.afcg.com/.lensing/fram_05.html you can clearly see what's
happening. The yellow spheres are using the mantra surface shader and
don't have any object reflection, refraction, transparency, or
displacement. This warping effect becomes a bit distracting during a
full animation sequence.
Has anyone experienced this before? Is it a standard artifact from DOF
