idle talk

I'm a little stuck... Click here to teach me more about this clue!

'converse of those doing nothing' is the definition.
I can't tell whether this definition defines the answer.

'converse of those doing nothing' is the wordplay.
I cannot quite understand how this works, but
'converse' could be 'talk' (I've seen this before) and 'talk' is found in the answer.
'doing nothing' could be 'idle' (I've seen this before) and 'idle' is located in the answer.
No letters remain.
This explanation may well be incorrect...

Can you help me to learn more?

(Another definition for idle talk that I've seen is " It's foolish to say".)

I've seen this clue in The Globe and Mail.
