enable motion blur causes crash while rendering, segmentation fault

[tinuz]

some of my DR hosts crashed while rendering a scene that rendered correctly without motion blur.
only happens when I have light cache as secondary bounces:

Would it be possible to send us the scene to: vraymaya@chaosgroup.com ?

I can't reproduce this error anymore, guess it was a fluke..
thanks anyway..
