  Can you please:

(1) post the result of sessionInfo()
(2) post *exactly* the code that you ran -- e.g. was it

       open3d()
       x <- sort(rnorm(1000))
       y <- rnorm(1000)
       z <- rnorm(1000) + atan2(x,y)
       plot3d(x, y, z, col=rainbow(1000), aspect=0.1)

?

  This seems to make some kind of superficial sense, but it
doesn't really -- if you look inside aspect3d() [which is eventually
called by plot3d -> decorate3d] you'll see that it has no effect.
On the other hand, 

       plot3d(x, y, z, col=rainbow(1000), aspect=c(0.1,1,1))

gives a bounding box that is skinnier in the x-direction.

  Nevertheless, it shouldn't crash.

  My sessionInfo():
