Still getting "index_of_running_image = '1'", which can only be correct
if it either
 a) refer to the storage_index, or
 b) the list index starts at 1


I do agree that both cases are inconsistent with the 'pri' index, but
that's the way it appears to be.

What does this look like on the MC73xx series? I know they can't store
more than one modem image, but there should still be a single element
list returned?
