Btw, I do get this message when running "xdg-open .": START /usr/bin/krusader -caption 'Krusader' --icon 'krusader_user' . krusader: Unknown option 'caption Krusader --icon krusader_user'. krusader: Use --help to get a list of available command line options. 'caption Krusader --icon krusader_user' is indeed not a valid command line option, but I'm not sure yet why the whole is treated as one option...
