Ok, so it appears that the xybot bot that fixes these errors is linking 
to an outdated Trac ticket.

I've seen a couple of these errors in the area I monitor recently, and 
they are produced in PL2. I can reproduce fairly easily by drawing a new 
way as follows:

place node A
place node B
place node C
click again on node B
press Enter to close the way
select node C
delete node C

You are left with what is ostensibly a simple way connecting nodes A and 
B, but node B is actually there twice.
