Comment:
I've attached a simplified testcase.
The problem is once again with edge segments being almost concidental but
not having an intersection, as shown in figure (note the lack of nodes
near the end point of the incoming offending red line):
[[Image(case.png)]]
The incoming line results in a new node and the edge merge code seems to
be choking on that, but fails to notice it before it is too late!
