This happens because srtm2osm sometimes misses out the longitude
coordinate.  At least an earlier version did that, when I tried recently
with the latest version I didn't get any problems but I may have just been
lucky.

I can anyway fix mkgmap so that it ignores points that don't have both a
latitude and longitude.
