I am reopening this bug; can yuou (Anton) provide some testcase for this
one? Don't you have something like

try:
   from yade import qt
   qt.Controller()
   someParameter=34534
except ImportError:
   pass

?

That would explain the difference, as if DISPLAY is empty or not set,
yade.qt raises ImportError. That would skip the assignment, then you'd
get different results.

Can you save the simulation right at the start and compare both?

I can't have a look in depth myself now.

Bug description:
First reported by Anton on the ML. The attached script produces different results for same initial simulation. By running it, it will produce 3 saved final simulations and 3 gnuplot plots (suffixed -00, -01, -02). They are different. It should be found out why.
