maximus doesn't undecorate on window opened

[Zelouille]

Maximus maximize but doesn't undecorate opened window.
You have to unmaximize then maximize each time you open a window to remove the decorations.
Nevertheless it works perfectly with some rare applications (see below).

System:
     Xubuntu 12.04.1 LTS LiveCD (virtualized).

Package:
    maximus 0.4.14-2 0

Step to reproduce:
    1. Install maximus
    2. Execute maximus
    3. Open thunar

What happened:
    Maximus succeed at maximizing it
    but failed at removing its window-decorations.

What I expected to happen:
    Automatic maximizing *and* removing window-decoration

Gconf settings (default):
    $ gconftool-2 -a /apps/maximus
        undecorate = true
        binding = disabled
        exclude_class = [Totem]
        no_maximize = false

Maximus fails with :
    thunar
    firefox
    thunderbird
    leafpad
    gmusicbrowser
    parole

Maximus works with :
    xfce4-terminal
    abiword

-------------------

I tryed to look at the code, and got it working "right" by removing the first condition (see below)

file:
    maximus/precise/src/maximus-app.c

line 308:
   /* Make sure the window supports maximising */
  actions = wnck_window_get_actions (window);
  if (actions & WNCK_WINDOW_ACTION_RESIZE
      && actions & WNCK_WINDOW_ACTION_MAXIMIZE_HORIZONTALLY
      && actions & WNCK_WINDOW_ACTION_MAXIMIZE_VERTICALLY
      && actions & WNCK_WINDOW_ACTION_MAXIMIZE)
    ; /* Is good to maximise */
  else
    return TRUE;

My tests show that
    actions & WNCK_WINDOW_ACTION_RESIZE
return 0 when it should not.
