Supplicant Errors When Running w/ D-Bus

I have been attempting to get running connman-0.63 and wpa_supplicant-0.7.3 on my TI / Mistral AM37x evaluation board with TI WL1271 evaluation module interface that has a WEXT-compatible driver.

Unfortunately, I get a few errors from the supplicant. Among them are a series of 'IWEVGENIE overflow' messages from the wpa_supplicant:

	...
	daemon.notice wpa_supplicant[28351]: IWEVGENIE overflow
	...

Are these typically indicative of a driver error or something in the supplicant?

I also get the following error following a scan:

	...
	IWEVGENIE overflow
	IWEVGENIE overflow
	IWEVGENIE overflow
	Received 4078 bytes of scan results (7 BSSes)
	BSS: Start scan result update 1
	BSS: Add new id 0 BSSID 00:27:0d:05:bf:55 SSID ''
	dbus: Register BSS object '/fi/w1/wpa_supplicant1/Interfaces/1/BSSs/0'
	BSS: Add new id 1 BSSID 00:16:c8:01:00:90 SSID '__'
	dbus: Register BSS object '/fi/w1/wpa_supplicant1/Interfaces/1/BSSs/1'

	wpa_parse_wpa_ie_rsn: malformed ie or unknown version
	process 31429: arguments to dbus_message_new_error() were incorrect, assertion
	...

which eventually leads to an abort in the D-Bus library:

	process 31429: arguments to dbus_message_new_error() were incorrect, assertion "reply_to != NULL" failed in file /source/dbus-1.3.1/dbus/dbus-message.c line 1333.
	This is normally a bug in some application using the D-Bus library.

Has anyone seen similar errors?

Best,
