Clue to minor problem (8)

I believe the answer is:

drawback

'problem' is the definition.
(a drawback is a problem or fault)

I don't understand how the remainder of the clue works.

(Other definitions for drawback that I've seen before include "Limitation, disadvantage" , "Fly in the ointment" , "Obstacle" , "Snag" , "Disadvantage, problem" .)

I've seen this clue in The Guardian.
