[OSM-talk] What to do with failed (Potlatch) save changeset?

[Steve Bennett]

While trying to save a changeset in Potlatch2, I got an error message
about version conflicts, and was left with a big chunk of XML.
Potlatch appears not to be able to do anything with it, but maybe I
can still salvage something from it.

I put it here: https://dl.dropboxusercontent.com/u/767553/OSM/failedupload.osm

Assuming I'm happy to simply lose any changes where there really is a
version conflict (which I am), what can I do with it? (I don't use
JOSM at all, so would prefer to avoid that hurdle if possible...)
