    Aha. Well spotted. The plot thickens.

    Killing gnome-settings-daemon under gnome is impossible (it restarts by
    itself each time), so I can't check, BUT starting it under KDE produces
    the same symptoms; the symptoms disappear after killing it. On the other
    hand, after killing xfce-mcs-manager (under xfce) the problem persists.

    However, the simple fact that the problem is now reproducible is a big
    step forward. Thanks!

    Ideas, anyone?
