You need to update plugins.

I had the same problem (ubuntu-11.04, with old version pre-installed!):

Solution: remove old packages including old plugins.

me@localhost:~/.josm$ dpkg -l | grep josm
ii josm 0.0.svn3751-2ubuntu1 Editor for OpenStreetMap
ii josm-plugins 0.0.svn24925-2 Plugins for JOSM
