If you can build your own copy of wpa_supplicant, put some debugging
prints in driver_wext.c in wpa_driver_wext_get_scan_results() in the
'case SIOCGIWESSID:' block to print out the code flow there.  What's
'ssid_len'?  Does the 'if (custom + ssid_len > end)' trigger?

Basically, we have to narrow down whether its the driver,
wpa_supplicant, or NM.
