Bug#930563: Can not start freecad

[Jean-Luc Lacroix]

Hallo Bernard,

You nailed it! That was the proprietary Nvidia driver that was the 
culprit. I uninstalled it and installed the debian nvidia-driver and 
nvidia-libopencl1 packages. Freecad is up and running now.

The nvidia-libopencl1 package is not strictly required by Freecad I 
believe, but I need it for darktable.

Thanks for your help.

Cheers.

Jean-Luc
