     Type:  defect    |      Status:  new          
 Priority:  medium    |   Milestone:  PostGIS 2.0.0
Component:  topology  |     Version:  trunk        
 Keywords:            |  
----------------------+-----------------------------------------------------
 When splitting an edge by a point it happens that the actual split point
 doesn't match the split edge endpoints, with the result of an invalid
 topology being created.

 Issue #1706 is partially due to this.
