NullPointerException occurs when downloading map data from OSM server

[cam_daw@…]

After clicking on the "Download map data from OSM server" button in JOSM, selecting any small area to download, and pressing the "Download" button. JOSM crashes with an Unexpected exception.
When looking at the main JOSM window the download looks fine - just has an error message that steals focus and won't go away unless you kill JOSM's java process.

This bug effects JOSM 2773 and JOSM 2801 (and probably JOSM 2741 see below for ticket #4307)

I did not suffer this from this bug sometime before JOSM 2773 (I can't be specific which version, but at least 4 or so days before JOSM 2773 was available JOSM-latest was working fine for me then).

A similar bug to this is ticket ​#4307
But unfortunately it was a poor ticket report.

My system information:
Ubuntu 9.10 x86_64 with latest updates installed,
Sun java 6 run time environment 6-15-1

This bug also effects Ubuntu 9.04 i386 with latest updates installed

This bug also becomes apparent when I have or have no plugins installed (to make sure I even deleted the entire contents of ~/.josm)

Please help as this bug stops me from being able to use JOSM-latest

I believe this has just been fixed in r2802.

What language do you have configured?

Please try and reopen this ticket if the issue is still there.

Ticket #4307 has been marked as a duplicate of this ticket.

[cam_daw@…]

Language = English (Australia)
Keyboard layout = USA Dvorak

The language key in JOSM's advanced preferences is blank.

I'll try out r2802 soon and will re-open this ticket if the bugs still exists.

Thanyou :)
