How to fix the "Failed to execute" problem

It looks like POVRay give a coredump under Linux if the env. variable DISPLAY is not defined even if I use the "-D" option. Try to define the DISPLAY variable on the Linux box (i.e. export DISPLAY=192.168.1.6:0) and then to run the worker scripts. This has always fixed the problem for me (and as doublececk if I unset DISPLAY I start to get the "Failed to execute" error).

I'm still investingating exactly why it happens only with JCGrid and how to fix this problem.
