Which version of ndiswrapper are you using?

wpa_supplicant did not like something in the WPA IE. Could you please
send 'iwlist wlan0 scan' output? Additionally, it could be useful to
test the attached patch which will make wpa_supplicant print out bit
more debug information when this messages is triggered. You can apply it
to 0.2.5 version by running
'patch -p0 < path_to_patch/wpa_ie_parse.patch'.

This is somewhat surprising error and I did not find a matching code
path from wpa_supplicant.. WPA IE parser is supposed to print out more
information about all error cases after that "could not parse" line, but
your debug log did not include any such information.. I would like to
first manually verify whether the WPA IE reported by the driver is
indeed invalid.

This is something that should be reported on ndiswrapper mailing list..
