[ekiga] CallWindow: Fixed crash when going crazy with the preview button.

    CallWindow: Fixed crash when going crazy with the preview button.
    
    The delayed "closing" and window destruction can now be safely
    interrupted if the user reenables preview after having stopped it and
    before the window was actually gone.
