Eric, Sorry for taking time to get back to you - I wanted to verify with the developers that this isn't expected behavior. You have correctly found a bug.
I wrote this up as bug number 8494 in the Kitware bug tracker. I used your very simple, excellent Point and Sphere source example listed below. If I missed anything, please feel free to modify the bug appropriately.

Monson Cc: Scott, W Alan; ParaView List Subject: Re: [Paraview] Losing data when clip multi-block Eric, I think we dealt with this problem since 3.4. I can't reproduce the problem with your first set of instructions on cvs head. Do you mind trying the cvs version? -berk On Fri, Feb 6, 2009 at 2:57 PM, Eric E.
