I was able to reproduce the problem.

It turns out the beacons generated by MadWifi in ad-hoc mode contain
some extra information, such as WPA data, even though WPA is not active
on the interface.  This must be a result of NetworkManager trying to
configure the interface.

You can mark the interface as unmanaged
in /etc/NetworkManager/nm-system-settings.conf as described at
http://live.gnome.org/NetworkManager/SystemSettings

Make sure to reload NetworkManager or reboot for the changer to take
effect.  You can use "cnetworkmanager -d" to confirm that the interface
is unmanaged.

You can also use the ath5k driver, which doesn't seem to have that
problem.

But even with ath5k, if you are not relying on NetworkManager for the
interface, it's better to mark the interface as unmanaged.
