Public bug reported:
Upgraded from Ubuntu 8.10 to 9.04 and lost all network connections.
Found out that it was it was a problem with dhcp3-client. See syslog

When I disabled the apparmor profile /sbin/dhclient3 the network
connection with NetworkManager works again. I don't know if this is a
bug in dhcp3 or apparmor, but its a bug that breaks the system. It's
hard to get back on track without a network connection...
