Exception raised trying to adjust an area

[wiml@…]

I was unable to reproduce this, but here is a backtrace in case it's useful.

I was editing the outline of Victor Steinbrueck Park http://www.openstreetmap.org/?lat=47.61012&lon=-122.34377&zoom=16 and selected a crosshair on its boundary in order to drag out a new node. (This was not the first edit I'd made to that polygon.) After I dismissed the exception dialog, the park looked unchanged, but as soon as I touched it the node I'd been attempting to create appeared (i.e., my drag had had the intended effect but the polygon hadn't been redisplayed with the change).

I kept on editing after this and didn't get any more exceptions, so I'm not sure why that particular edit caused an exception. I had previously been editing near http://www.openstreetmap.org/?lat=47.61393&lon=-122.35057&zoom=17 .
