JOSM creating nodes at 0,0

[rasher]

I regularly load the area around 0,0 to see if any junk has ended up there. Lately (since a few weeks) it appears that JOSM will sometimes, under some condition create nodes at 0,0 while the user is editing a completely different area.

An example here, where the nodes were even part of a way, but usually they are just untagged and unused nodes:

This is not the most helpful bug report I've ever created, I'll admit. I guess it's possible that it is somehow user error but if it is, maybe the validator should scream bloody murder if the user tries to create anything at 0,0?

Sounds reasonable, there could also be a warning for very long way segments.

Some time ago there was a discussion about that topic in the de-forum (german only):
​http://forum.openstreetmap.org/viewtopic.php?id=11178

Back in April the problem was still around, e. g. changeset 7880161.

I'm not sure if it's really just a "josm only"-problem.

Still a problem: ​http://www.openstreetmap.org/changeset/20047152 contains a node created at (0,0)
