Minor quibbles (4)
I believe the answer is:
nits
'minor quibbles' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nits that I've seen before include "Tins of parasitic insect eggs" , "Head louse eggs" , "Eggs; stupid people" , "Eggs of lice" , "Fools" .)
