Well, if it fixes your problem, at least prevents a crash, I am ok to
commit it. I don't see any regressions here.

Please, let me know.

Title:
  Saving, loading simulation with erased bodies crash.

Status in Yet Another Dynamic Engine:
  Fix Released

Bug description:
  Here is the bug :

  - launch yade (for example without any script)
  - add a sphere : O.bodies.append(utils.sphere((0.2,0.2,0.2),0.006))
  - delete it : O.bodies.erase(0)
  - save yade's universe : O.save("./test")
  - quit yade
  - launch yade
  - load the file : O.load("./test")
  ->segmentation fault

  I think it's because when you erase something the size of O.bodies (etc...) doesn't change and now contains an empty value. (the c++ array may not be dynamic ?)
  So when the O.load() function is called, yade try to load a non-existant body ?

  Maybe this can be fixed by changing the load() method ?

  I joined the debug output.
