Looks like libiw...
Here's a similar segfault if I run netcfg outside d-i and drive it by hand
(on a different system):
write(3, "GET netcfg/choose_interface\n", 28) = -1 EDESTADDRREQ
(Destination address required)
read(0, 0 eth0
"0 eth0\n", 4096) = 7

ifr_flags=IFF_BROADCAST|IFF_MULTICAST}) = 0

-1, 0) = 0x40019000
read(5, "eth0 foo\n", 4096) = 9
close(5) = 0

ioctl(3, SIOCGIWMODE, 0xbffff588) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---

Next step IMHO is writing a small test case that runs the libiw function
called first by netcfg and it will probably also crash.
