It turns out that this bug doesn't show up, when I need (with debug
options you provided)
I found that I enabled hw encryption, although it is disabled by
default, and I suspect that this is due to that
I see clearly now that this warning (as expected) occures, just after
association, when wpa_supplicant sets keys.
I look at source for further information.

Sounds like you can easily reproduce it ... would it be possible to get
us some extra logs for this problem? Could you please run with debug
0x400002 ?
Thank you very much
