The import code was making wrong assumptions for the ASEG volumes where the label 7 was missing (white cerebellum). I removed this test, and now it reads everything as if it were coming from FreeSurfer >= 5.
Maybe I'm breaking the import of ASEG atlases processed before 2009, but I could not find any old enough example dataset to try making something smarter...
Can you try again importing the folders with this fix?
