Ok, PowerDevil is receiving the message but:

Breakpoint 1, PowerDevilDaemon::suspend (this=0x1d910b0, method=2) at

Hum. So it seems that ConsoleKit thinks that the session is not
active? And indeed:

Session3:
        unix-user = '1000'
        realname = 'kronos'
        seat = 'Seat2'
        session-type = ''
        active = FALSE
        x11-display = ':0'
        x11-display-device = '/dev/tty7'
        display-device = '/dev/tty1'
        remote-host-name = ''
        is-local = FALSE
        on-since = '2010-10-04T08:26:39.557512Z'
        login-session-id = ''

This is probably Debian bug #598150, so KDE is innocent :)
