Stage carpenter may be in a jam (6)

I believe the answer is:

quince

I believe this clue is a double definition.

'stage carpenter' is the first definition.
(character in A Midsummer Night's Dream)

'may be in a jam' is the second definition.
(as in quince jam)

(Other definitions for quince that I've seen before include "Peter -- (A Midsummer Night's Dream)" , "Peter --- (MND); fruit" , "Cinque (anag) - fruit" , "part-time Athenian dramatist" , "Dream chippy" .)

I've seen this clue in The Times.
