Dunno. Your function that does all of the completion,
`edsquery-return-addresslist' isn't shown. 

The error message is saying that function `ad-Orig-minibuffer-complete' expected
a number or a marker but received the list of strings. 

You also apparently advised the standard function `minibuffer-complete', and
that code isn't shown either. So it's difficult to guess what is the problem.

No comprendo. What isn't breaking what cdr cell down into what components?

FWIW, I see nothing wrong with the call to completing-read. The problem is
likely in your completion function `edsquery-return-addresslist'.

The error message should help. Look at your advised version of
`minibuffer-complete', `ad-Orig-minibuffer-complete', and see why and where it
expects a number or marker. Look at why your function `eds...' gives it a list
of strings in that place instead. Perhaps try unadvising `minibuffer-complete',
at least for testing.
