Netcfg NULL pointer dereference in custom debian-eeepc d-i

I am try to build a custom d-i for debian-eeepc that has the atheros wireless and ethernet modules included. Process used is from the following wiki pages.


The build appears to have gone well, and I can boot and start the installer. When the installer gets to configuring the network, netcfg oopses the kernel with a null pointer dereference. If I switch to vt2 before doing any tasks then I can bring up ath0, set an essid and wep key and get a dhcp lease. I tried bringing up both cards before getting to the configuring network stage but it still oopses with netcfg. However, if the ethernet cable is plugged in during configuration, then I can chose either ethernet or the wireless card and from there on all seems to work fine. The oops is below but may have some errors as its hand typed.
