Hello Lucy, just for your information. I'm encountering similar problems when using paraview3.5 version compiled with OSMesa-support in pvpython mode. Executing pvpython scripts fails if I try to save the pipeline result to a .png od .jpeg file.
That's why I compiled a non-OSMesa version of paraview3.5 which I use in parallel pvpython mode. I'm not sure what caused this behaviour of the paraview version compiled with OSMesa support. Maybe the problem is caused by a from environment setting running in script mode. If I use the mentioned OSMesa paraview version in parallel GUI mode (client + server) everything runs fine, even saving screen-shots to .png or .jpeg file. Maybe somebody knows a solution.
