Comment:

 The shapefile worksforme!

 For the "OSM" file: that's not actually an .osm file, it's an .osc
 (OsmChange) file. Whereas .osm files have an <osm/> root element and
 <node>, <way> and <relation> children, .osc files have a different
 structure with <create/>, <modify/> and <delete/> children.

 .osc is intended for distributing changes to existing data and is
 therefore not really suitable for bringing data into an empty P2
 background layer. However, I've added a small workaround -
 
https://github.com/systemed/potlatch2/commit/ffe3474fc2f3426b5a8f9c909ea5632b93295120
 - which will parse the <create/> section ''only'' of such files. This
 should enable you to load files like that.

 Bear in mind that there's currently no support for "pulling through"
 relations, so you'll need to reconstitute the multipolygon relation when
 you do so. On the other hand, P2 now has a lovely easy "create
 multipolygon" button!
