(env)vagrant@precise32:/vagrant$ ogrinfo davis.osm multipolygons
Had to open data source read-only.

Which hopefully shows I have all the right libraries installed. I've attached the 'davis.osm' file for reference.

This is on Django 1.5.4 with PostGIS 2 + gdal 1.10.0

I cannot reproduce this issue with Django 1.5 and gdal 1.9.0. I suspect this is either an issue on your system or a compatibility problem with gdal 1.10 (which I cannot test myself currently).
