hostapd and b43: can do unencrypted, cannot do WPA - continued

[Francis Galiegue]

I managed to drop the sigsegv when setting up WPA, however, the WPA
negotiation completes but... The station is deassociated just
afterwards due to inactivity (uh, what activity? I didn't even get the
chance to send anything!):

Related or not, it also happens that, in unencrypted mode, the same
station also gets disconnected to to inactivity once, twice, before
the AP lets it, at last, send a DHCP request.

What could be the problem?
