###############
(ROX-Filer:78077): Gdk-CRITICAL **: gdk_x11_atom_to_xatom_for_display:
assertion `atom != GDK_NONE' failed
The program 'ROX-Filer' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAtom (invalid Atom parameter)'.
  (Details: serial 246 error_code 5 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
