I've a different problem with wireless that Johannes is investigating
for me on linux-wireless; but here's a patch that he pointed me to
along the way, didn't help my issue but I expect it will help yours...
Subject: cfg80211: don't set privacy w/o key
When wpa_supplicant is used to connect to open networks,
it causes the wdev->wext.keys to point to key memory, but
that key memory is all empty. Only use privacy when there
is a default key to be used.
