NPE after downloading certain gps data

[Cobra]

What steps will reproduce the problem?

1. download data for this bbox with raw gps data: ​http://www.openstreetmap.org/?minlon=8.2273865&minlat=48.1935565&maxlon=8.2340813&maxlat=48.1987057&box=yes

What is the expected result?
osm and gps data getting downloaded and displayed.

What happens instead?
OSM data is displayed correctly.
While loading gps data josm crashes, the window elements aren't painted.
After clicking "Do nothing" you can delete the gpx layer and josm seems to work again.
If you zoom/pan, josm crashes again: "java.lang.NullPointerException", no more details.

Other areas seem to work fine as far as I tested.

r4125 is working fine, r4131 is broken.
I'll test more revisions later if nobody has a clue what's wrong here.

[Cobra]

r4129 introduced this bug.

[stoecker]

Sorry does not happen here. Can you save the GPS layer? Does it result in same error when loaded?

If not please specify the exact boundary to download.

Code says last should never be null when this is true!. Seems this is wrong, so there may be a bug which has been hidden previously :-)

[Cobra]

Right-clicking the layer produces the same error.
I could save the layer only after hiding it.

Loading this file causes the same error.

I've tested this with r4136 (current latest) and r4137 (current SVN, built locally), no difference.

[Cobra]

this file should crash josm

[malenki]

Not confirm with neither the description in the OP nor the last appended file using Josm r4136 and r4137.

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

[stoecker]

Please attach your config file as well (strip username/password).

[Cobra]

This setting triggers this bug:

draw.rawgps.lines.force=true

I renamed ~/.josm to start from scratch and tested with r4138.

[stoecker]

In [4143/josm]:

fix #6463 - fix NPE, remove some of the new toolbar warnings for image menu
