Network Manage/DBus problem? (Ubuntu/Feisty)

["W. James MacLean" <maclean eecg toronto edu>]

I can't seem to get Network-Manager to run properly under Ubuntu
(Feisty). The 'nm-applet' icon shows in the panel, and it lists
available wireless networks, but when I try to select one, nothing
happens. The following error message does appear in /var/log/syslog:

Jul 12 15:43:07 localhost NetworkManager:
nm_ap_security_new_deserialize: assertion
`dbus_message_iter_get_arg_type (iter) == DBUS_TYPE_INT32' failed
Jul 12 15:43:07 localhost NetworkManager: <WARNING>^I
nm_dbus_nm_set_active_device (): nm-dbus-nm.c:288
(nm_dbus_nm_set_active_device): Invalid argument (wireless security info).


Now, I don't think it's a hardware problem, as if I boot the same
machine with the Feisty LiveCD, Network-Manager appears to work OK.
I'm guessing it's a configuration problem, but other than
/etc/network/interfaces, what else could be wrong? What other
configuration files affect Network-Manager?

Thoughts?
