I think there must be a very large number of GPS trace points at the intersection of the equator at the prime meridian (what’s that place called anyway?).
I’m afraid I’ve been fool enough to add quite a few of these myself! Oops. Sorry.
I’ve modified one of the gpsbable scripts that I use to prepare NMEA files, chopping out anything around (0,0), so all should be fine from now on.

The intersection of the Equator and Prime Meridian is called “the origin.”

Ah! Cool. Thanks. :-)

Also known as “null island”. A lot of stuff ends up there. Not just GPS traces but nodes, etc. You also see a lot on the equator that obiously don’t belong there where just one coord got 0.0 and I assume the same happens along the meridian. I have also heard the poles collect nodes too but haven’t seen it myself.
