I've had problems with vtk and ATI Mobility Radeon 9600... basically 
rendering anti-aliased fonts would cause a crash (it also depended on 
the size and font). Changes to vtk last August fixed it for me though.

and the faq:

If you're using an old version of vtk, upgrade to a version that was 
built after last August and see how it goes.
