Right now I'm getting lots of 500 errors on attempted uploads. It may be a 
coincidence, but all the errors appeared when attempting to modify (i.e, 
move) an existing node. Creating new nodes, segments, and ways, 
and modifying existing ways as well as deleting segments seemed 
unproblematic. Probably unrelated, at the same time Potlatch does not seem 
to be able to download any ways at all. Some examples of JOSM output:
