josm crashes once data is collected, just before opening the editing window

[francois@…]

When I want to grab the data for that area,

​http://www.openstreetmap.org/?lat=46.9665&lon=-2.2228&zoom=12&layers=0B00FFF

The data collected from osm are available here, (as I can't attach more than 256k) :
​http://arvernes.dyndns.org/
file : map.osm

This is the crash I get with the latest svn code :
