Correct; when NM starts up it requests a scan from wpa_supplicant.  That
scan usually happens immediately, but sometimes drivers will reject the
scan for various (usually wrong) reasons.  Unfortunately there's no way
to figure out yet that a specific scan request that NetworkManager made
has been rejected so that NM can retry it.  Drivers like ath5k/ath9k
seem to reject scans much more often than iwlwifi for example.  You can
often see in 'dmesg' output when scan requests have failed.

This is something we have to work on in wpa_supplicant first.
