[Paraview] Crash with Parallel Pvserver, Off-screen rendering

[Gregory, David C CIV NSWCDL G24]

Hi-

I'm running a CVS snapshot from 20 Sept of Paraview 2.5, compiled with
mpich-gm, Mesa-6.5.1 and off-screen rendering enabled in cmake.  I also
have a version compiled with mesa and off-screen but without mpi.

I start paraview as follows:

/paraview-cvs-mesa-nompi/bin/pvclient -rc

/paraview-cvs-mesa-mpi/bin/pvserver -rc -ch=headnode
--use-offscreen-rendering

If I un-check the "compositing" box in the GUI, which as I understand
things, disables compositing and does all rendering on the head node,
paraview runs fine.

However, if I turn compositing on, the SERVERS crash immediately if any
data is loaded for display, and I get a message from the client which
informs me that connection to the server has been lost.  There are no
X-related errors in stdout or stderr - only a message which gives an
error in the vtk server connector.

Is this likely a bug or a configuration problem?
