Is it 100% reproducible on your system ?

Can you tell me how many screens and printers do you have installed ?

Summary: Cannot launch JOSM[Patch] Cannot launch JOSM (division by 0 when getting screen info)

I can't remember if there was a good reason to iterate on all screen configurations. Here's a non-tested patch (I have only one screen right now) that checks devices are really screens (and not printers or image buffers), considers only the default configuration, and avoids the division by 0.

@team: tests are welcome :)

8021.patch works, and JOSM launchs without any problem.
alos confirmed the multi-screen issue, unpatched JOSM (version 5485) does launch if the extenal screen is disconnected
thanks Don!
