NM 0.9.8 doesn't realise that DHCP worked

[Bastien Nocera <hadess hadess net>]

Heya,

I'm using rawhide on my laptop, and I can get the network to work in
sporadic 30 second bursts, as NM doesn't realise that dhclient got an IP
address:
Feb 26 13:35:16 sirocco dhclient[1177]: bound to 192.168.0.24 -- renewal in 17055 seconds.
Feb 26 13:35:59 sirocco NetworkManager[576]: <warn> (wlan0): DHCPv4 request timed out.

Feb 26 13:35:59 sirocco NetworkManager[576]: <info> (wlan0): device state change: ip-config -> failed (reason 
'ip-config-unavailable') [70 120 5]

Any ideas what might be causing this? I get the same problem on wired and wireless networks.

dhclient-4.2.5-7.fc19.x86_64
NetworkManager-0.9.8.0-1.fc19.x86_64

Cheers
