Woman's bad breath (6)

I believe the answer is:

bertha

'woman's' is the definition.

'bad breath' is the wordplay.
'bad' indicates anagramming the letters.
'breath' is an anagram of 'BERTHA'.

(Other definitions for bertha that I've seen before include "The bar (anag.)" , "Female name; Big -, World War one German howitzer" , "Breath (anag) - girl's name" , "collar" , "43-ton German howitzer, Big _____" .)

I've seen this clue in The Times, The Telegraph and The Sun.
