It's impossible to minimize the front window (clicking on its minimize widget just invisibly minimized the owner of the modal dialog).

OK, this definitely sounds like a bug caused by an obscure behaviour.
Can you file a new bug for this and let me know of applications which
will open modal dialog windows while they are not in focus ? (eg, not
on user interaction)

Clicking on their icon in the launcher does nothing except change which programs menu bar is present in the menu area, and that window (the one that got its menus displayed) now has keyboard focus, but does not get mouse events and, because its hidden behind another window, is invisible. Because of the keyboard focus issue, I've typed things I thought were going to one program but ended up in another.
