Comment (by hamish):

 a shapefile from ogr2ogr gives ok extent.
 (another bug is stopping me importing that, duplicate column names)

 {{{
 $ ogrinfo -ro -al track_points.shp
 INFO: Open of `track_points.shp'
       using driver `ESRI Shapefile' successful.

 Layer name: track_points
 Geometry: Point
 Feature Count: 4532
 Extent: (170.168993, -46.055889) - (170.724047, -45.742630)
 Layer SRS WKT:
 GEOGCS["GCS_WGS_1984",
     DATUM["WGS_1984",
 ...
 }}}

 aaaah, here is why:

 {{{
 INFO: Open of `waypoints.shp'
       using driver `ESRI Shapefile' successful.

 Layer name: waypoints
 Geometry: Point
 Feature Count: 0
 Extent: (0.000000, 0.000000) - (0.000000, 0.000000)
 Layer SRS WKT:
 ...
 }}}

 the GPX import creates 5 layers:
 {{{
 route_points
 routes
 track_points
 tracks
 waypoints
 }}}

 but my GPX file only has tracks in it. so some of the other layers have no
 extent (and no features), but v.info picks up the 0.0 anyway.
