I just tried some things on our Beowulf cluster as pvserver and my
workstation as the pvclient. I tried opening up the wavelet source
( worked ), contouring ( worked ), color by process id ( worked ), but
as soon as I clip anything the pvserver dies with a segfault.

The pvserver complained as below but it was run with
--use-offscreen-rendering. The server was built with mesa as the only
GL.
