I compiled the git version of exo on Dec 19, 2012 and exo-open wouldn't launch .desktop files, saying that "exo-open-CRITICAL **: Launching desktop files is not supported when exo-open is compiled without GIO-Unix features". To reproduce, try: exo-open anything.deskop I found additional information here: http://git.xfce.org/xfce/exo/commit/?id=d92e4797d07001f9396f61b2fdb6f48ee8970171
