The chaps are going round this time, one has complaints (8)
I believe the answer is:
'complaints' is the definition.
(I've seen this before)
'the chaps are going round this time one' is the wordplay.
'the chaps' becomes 'males' (I've seen this in another clue).
'are going round' means one lot of letters goes inside another (some letters go around others).
'this time' becomes 'AD' (AD, Anno Domini, as opposed to BC, Before Christ).
'one' becomes 'i' (Roman numeral).
'males' going around 'adi' is 'MALADIES'.
'has' is the link.
(Other definitions for maladies that I've seen before include "illnesses" , "Diseases, ailments" , "Complaints" .)
