I have the same problem.  There appears to be something broken about how
NetworkManager is invoking dhcpclient.  If I run it by hand, NM still
doesn't think that it's connected, but I get network connectivity.  syslog
is full of messages like:

Aug 21 10:33:19 wanderer NetworkManager[642]: <info> dhclient started with pid 17691
Aug 21 10:33:19 wanderer NetworkManager[642]: <info> Activation (wlan0) Stage 3 of 5 (IP Configure Start) complete.
Aug 21 10:33:19 wanderer dhclient: Internet Systems Consortium DHCP Client 4.3.1
Aug 21 10:33:19 wanderer NetworkManager[642]: <info> (wlan0): DHCPv4 client pid 17691 exited with status -1
Aug 21 10:33:19 wanderer NetworkManager[642]: <warn> DHCP client died abnormally

Downgrading network-manager to 0.9.10.0-1 fixes the problem.  It looks
like something went wrong with the NMU.  Copying Micah.
