Francois-Xavier,
  There are two different QuickSurf code paths, one for color-per-atom and one
for color-per-surface.

Does it matter which coloring method you have active when you
create the QuickSurf representation? Does it also crash if the
coloring method is set to "ColorID" prior to changing the rep
to QuickSurf (color-per-surface)?
I'm guessing that the crashes that have been reported likely occured for
color by "Name", which is the color-per-atom code path, but I want to
determine whether it crashes in both cases or only one.
If you can test by setting the rep coloring method prior to changing
from say, Lines, to QuickSurf, that would help me determine more details
about what is going wrong here.

Best,
  John Stone
