When selection tool is used, josm CRASH

[fatbozz]

I was editing some land. I download BBox (with gpx) , because i load some GPX.
Some error happened ( unexpected eof from server, when GPX files arriving ), i clicked ok, no any other option to choose :)

I edit sometime, then i used relation and scroll to another place, download some WMS data and used shortcut for selection tool. And this is my product... error.
This errorbox cant be closed, still reportbug, ok, report bug ok, when "do nothing". nothing happens.

Can you try to make it reproducable?

Althought that may be an error without any steps to reproduce it it cannot be fixed.
Very likely some internal data structure was wrong after ther partial load.
