Description of problem:
Changing network interface after configuring it for static IP causes a traceback in the installer.

Version-Release number of selected component (if applicable):
11.4.1.62

How reproducible:
always

Steps to Reproduce:
1. Run installation from Fedora 10 i386 DVD with all defaults on a system with more than one network interface.
2. Select "Advanced Storage Configuration"
3. Select "Add iSCSI target"
4. For the first interface (eth0 in my case), uncheck DHCP, enter IP 192.168.0.23/255.255.255.0, gateway 192.168.0.1, nameserver 192.168.0.1
5. Press "OK".  After some time, an error message appears "Error configuring network device".  Dismiss the message by pressing "OK".
6. Select another network interface (eth1 in my case).  I'm doing it with the keyboard, as I have no mouse on that system.
7. Select the original network interface (eth0).
  
Actual results:
Traceback (most recent call first):
  File "/usr/lib/anaconda/iw/netconfig_dialog.py", line 79, in _netdevChanged
    if self.network.gateway: self.xml.get_widget("gatewayEntry").set_text(self.network.gateway)
AttributeError: Network instance has no attribute 'gateway'

Expected results:
There should be no error configuring the network device in the first place.  And if there is any error, there should be no traceback!
