not possible to open a local file

[anonymous]

What steps will reproduce the problem?

1. Open JOSM
2. Klick on Datei/Öffen (i.e. File/open)

What is the expected result?

I planed to select the directory with sample.osm in it

What happens instead?

The Errorwindow poped up. and a Window to select files. (welches nicht sonderlich hilfreich war, da ich dem Verzeichnisbaum nicht weit genug runter kam. nur bis /home/user ich wollte aber zu /home/user/downloads) It wasn`t possible to reach /home/user/downloads

Please provide any additional information below. Attach a screenshot if possible.
