Short track with nans sprinkled about

I've been on 1.5 for a full day and no crashes, to include several 15 second
trips through a tunnel where Marble previously reliably crashed.

The previous behavior was to freeze upon entering the tunnel, and then segfault
several seconds after exiting the tunnel.

Current behavior has one oddity: the track ends when the fix is lost as you
might expect, but does not appear to pick up again, until toggling "Show Track"
twice, whereupon the track is shown as you would expect.  This is consistent
with previous behavior where tracks would disappear for some reason, but would
come back after toggling " Show Track".

I've attached a short track with nans saved previously; you might find it
interesting.  It shows lines from the displayed discontinuities converging
toward the upper left edge of the screen and to a point beyond it.  When you
hold the left mouse button down on the map, or otherwise manipulate it, you get
a sort of a flood fill effect.  It seems to have no permanent ill effects. 
This is consistent with every "funny" track I have seen.
