JOSM cannot deactivate validator plugin

[anonymous]

I just updated JOSM from rev 761 to rev 935. After I downloaded an area, JOSM displayed me a message box that an unhandled exception occurred in the plugin 'validator'. I'm using rev 6389 of the validator plugin, which seems to be incompatible to the latest JOSM rev. Anyway, the the error message gives me the ability to disable the plugin. But as I pressed 'yes' to disable the plugin, I got another message stating that "The plugin could not be removed. Please tell the people you got JOSM from about the problem." And that's what I have done with this ticket ;-)

BTW, here's the exception the plugin threw:

Seems to work here, at least with a randomly created exception in the Validator plugin. Can you look at your JOSM preferences file (usually ~/.josm/preferences under Unix) and give us the line that starts with "plugins=..."?
