[Paraview] Segfault in ParaView 4.4 RC2

[Utkarsh Ayachit]

NVM...those were from your original tarball. I thought they were
generated as an output from my run :). It's indeed an X issue in both
cases. Couple of options:

1. Do a Mesa3D build locally on the VM. Then set LD_LIBRARY_PATH to
point to the generated OpenGL libs and run ParaView/Catalyst. That'll
avoid using the GL libraries provided by virtualbox.
2. Do a OSMesa build and then rebuild ParaView/Catalyst to use OSMesa.
That'd mean you can't have the Qt UI in the same build, but Catalyst
and other scripting executables will work. That would avoid the X
issue all together. This Wiki [a] describes how to get a OSMesa
enabled ParaView build.

BUT the generated file has a big black area (see image_2.png attached). Also I see a window appear for a brief moment with the correct (full) view, then it disappears. I don't know why I get that.
