10269	Null deref in GpxLayer.java:755	glebius	team	"Under certain circumstances trkPnt.customColoring is Null. To reproduce the problem, the following is required:

1) draw.rawgps.large=1
2) LiveGPSPlugin enabled and connected to gpsd. Hint: use gpsfake from gpsd package to reproduce on a computer without GPS receiver.

I haven't yet investigated the problem very good, but my current guess is the following: there is a race between GpxLayer.paint() and the LiveGPSPlugin adding new points to the GPX.

In line 552 there is cycle
== for (Collection<WayPoint> segment : data.getLinesIterable(null))
, that adds customColoring to every trackpoint.

Later in line 631 we have same iterator that fills in visibleSegments linked list. And later in that list in line 755 we encounter a trackpoint without customColoring initialized. So, I guess, that between iterator in line 552 and iterator in line 631 the ""data"" is modified with new points."	defect	closed	normal	14.07	Core		fixed
