Hi Fabio,

Are you running from a bash shell under a terminal started from the XWin Server 
shortcut or X Applications Menu?

Those variables are defined in my shell:

	$ echo $XDG_CURRENT_DESKTOP $XDG_MENU_PREFIX $XDG_RUNTIME_DIR
	X-Cygwin xwin- /run/user/######/

-- 
Take care. Thanks, Brian Inglis              Calgary, Alberta, Canada

On the same machine, octave built for Windows executes correctly the same command. I have observed the same behaviour also on other Windows machines running Win7 or other graphic adapters.
