Regarding my problems raytracing on my debian/testing machine. The system has 128mb of ram.
I have attached a pymol session file. To generate the session file, I
loaded a very simple molecule into pymol. After loading the session file
and executing the ray command I get a segmentation fault. The tail end
of pymols output to the shell is show below. As you can see below, while
pymol starts up I recieve an error complaining about 'PYMOL_PATH'. I
don't know if this error is related to the problems I am having with ray
tracing. Please let me know if you would like any more information.
