NetworkManager: IP address == Broadcast address?

[Patrick]

Hi,

Problem: Internet via a Nokia from a laptop with F10 x86_64 does not (no 
longer?) work. Assigned IP address on laptop is the same as the 
broadcast address.

A laptop with up-to-date Fedora 10 x86_64, NetworkManager version 
0.7.0-0.12.svn4326, a Nokia E71 and a USB cable for use between the 
Nokia and the laptop. The Nokia has a working permanent GPRS Internet 
connection. Steps I do to setup a link between the laptop and Nokia:

1) I added the T-Mobile mobile broadband profile in NetworkManager
2) I plug the USB cable into the phone and laptop and select "PC Suite"
    on the phone when asked
3) I select the T-Mobile profile in NetworkManager
4) NM starts chewing and reports after a few secs that a connection has
    been setup

Result:
Internet no longer works on the Nokia nor from the laptop via the Nokia. 
In NetworkManager I select "Connection Information" and notice that the 
IP address and Broadcast address are the same. Pings fail except to the 
public IP address assigned to the laptop.

Question:
Is this a bug? I'm no IP addressing expert so IP address == broadcast 
address might be valid.

FWIW I think this used to work fine when I initially did a fresh install 
of F10 on the laptop.

In /var/log/messages I see:
ifcfg-fedora:     error: Missing or invalid IP4 prefix '0'

Here is some more logging when setting up a connection:

Any idea?
