Could you please attach the gpx file?

[dieterdreist]

unfortunately I can't because it is copyrighted and I'm not the copyright holder. But I can confirm that of many files (all handdrawn in Garmin's old mapsource software, saved as gdb and converted with gpsbabel in gpx or exported directly as gpx from mapsource) only very few did convert correctly to OSM data (most resulted in empty files), but at least one did, so it's probably not an issue for "true" gpx tracks (device recordings with consecutive timestamps).

Replying to dieterdreist:

it's probably not an issue for "true" gpx tracks (device recordings with consecutive timestamps).

Then not an issue at all. I tried with a gpx track and it works fine. Tell whoever created your invalid copyrighted file to fix it.
