Changes (by strk):

  * status:  new => closed
  * resolution:  => invalid


 It seems that the input is still not properly noded.
 In particular there's a linear intersection between the line with 5
 vertices and the one with 6. Passing the geometry under unaryunion turn it
 to a 4 lines geometry, and that one successfully polygonizes.
