Question #187904 on Yade changed:
https://answers.launchpad.net/yade/+question/187904

Klaus Thoeni gave more information on the question:
Any Red Hat user around? Can you save and load simulations? Yade is running 
but I can't save or load simulations.

Does anyone have an idea where the problem could be?

Thanks,
Klaus
