Thanks for confirming. Actually, if I delete the traces and recreate them, 
everything is fine. But if I save and reload, the problem comes back. 

If I export the pcb to Gerber, the two shorts are in the photoplotter file,
which is really annoying and shows that this is not a spurious display artifact.

This is a a reduced test case from a larger PCB. I can further remove
J1 and still see the problem. At this point I think that the test case is
simple enough (1 polygon, 2 lines, 4 pads) for the people who wrote/know t
he dicer code to step in.

I use the latest git code, with even a few local changes to the git 
exporter, but they should not affect this issue.
