Summary0000189: vtk 4.2 segfault assemplytest
DescriptionWhen running the following example on several computers running both Redhat 7.3 and Debian SID with VTK 4.2, python consistently segfaults when positioning the mouse in the center of the spheres and pressing 'p' to pick the assembly. If one has problems "hitting the spot", try moving the mouse pointer around while repeatedly striking 'p'.

The example could not be repeated with fewer than 7 spheres/actors in the assembly.

Backtrace from running 'gdb python' then importing the assemblytest:

 The patch works great. Thanks.

I needed it for VTK 4.4. I was getting messy crashes. This solved the problem.
