Best I can say is that it seemed to happen after a failed connection.
It would connect and disconnect a few times and work fine, but if it
failed to connect for any reason (mostly mismatched settings between
AP and wpa_supplicant.conf) then the bug would occur. So,
wpa_supplicant would up the interface, try to connect, fail, down the
interface and exit, then the next loop of my script (with a different
conf file) would start and wpa_supplicant would be unable to up the
interface.

Hope that made any sense, because it didn't to me :-)
