A quick check you can do is to evaluate (after Gnus has loaded):

(nnmaildir--param "nnmaildir:inbox" 'expire-age)

And see what that gives you. I'm not entirely sure that
"nnmaildir:inbox" is correct, and I wonder if the problem you're seeing
comes from the fact that your nnmaildir server has a blank string for a

The real check would be to edebug `nnmaildir-request-expire-articles'
and see what it's doing. You may already be familiar with edebug; if not
then put point inside that function and hit "C-u C-M-x". The next time
expiry runs the process will halt and display this function, and you can
step through it with <SPC>. As point passes over various sexps, their
return value will be shown in the minibuffer. Look for the value of
"pgname", and the 'expire-age parameter, and later the 'expire-group
parameter. Something in there should jump out at you as "wrong".

(Apologies if you already know edebug.)
