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!
