This bug still occurs, even when there's no wifi connection and the
RF_KILL bit is set (radio disabled, so that wifi is not possible).
The suspend doesn't fail, but is just very slow (several dozens of
seconds, which is unacceptable).
It seems to occur only when there is no Ethernet cable plugged in
(perhaps the wicd daemon can detect it and doesn't try to do anything
in such a case?).
After a Fn-F1 to put the machine into sleep, as I was seeing that
it was not put into sleep yet, I did a ps and found that
/usr/lib/pm-utils/sleep.d/55wicd was running, with a child
/usr/share/wicd/daemon/suspend.py; the 55wicd script has:
wicd_suspend()
{
# Put wifi interface down
/usr/share/wicd/daemon/suspend.py 1>/dev/null 2>/dev/null
RETVAL=$?
}
The /var/log/syslog file shows that dhclient is started several
times to do a DHCPRELEASE on wlan0 (even though wlan0 isn't up),

and some daemons were reconfigured, again, several times (this may be
a consequence of /etc/network/if-down.d/ scripts), before the machine
entered sleep:
