Title:
  Some LPE alterates some curves segments with parallel handles

Status in Inkscape:
  Confirmed

Bug description:
  Attached is a curve segment with handles going in opposite directions
  along parallel axes. LPE Rotate Copies draws it erroneously, as seen
  if one select the object with the Node Editor (F2).

  This happens for example in Bend LPE and in Rotate copies LPE

  When moving around any node, or the segment itself or the entire LPE
  object the curvature at the right node suddently inverts.

  The only way I found to remove the problem without changing my
  original curve is adding a node at any place on it.

  Otherwise, breaking the parallelism between the two handles result in
  a correctly redrawn curve too.

  Inkscape 0.91 devel ppa on Kubuntu 14.04
