No idea, but a bit more stress testing did reveal a similar problem here.  
After I associated with the AP w/ hidden SSID I changed the channel via 
webinterface.  The disconnect resulted in the exact problem you were 
having.  Only stopping and restarting wpa_supplicant fixed the issue and 
I got associated on the new channel.  Not sure what happens there yet, 
but something seems to get stuck in an undefined state.
