Vauxhall Vectra stalling at low revs

I own a Vauxhall Vectra C 1.9 diesel. It has a manual gearbox and a DMF. The problem I have is when the clutch is not engaged. The car runs smoothly and then stalls, with a clicking noise. This happens after starting or when stopped at lights. When I engage the clutch - the engine runs smoothly.

Just to clarify I have no other issues with the clutch. Good bite and no slip when accelerating hard. If I change the idle rpm from 800 to 1000 the stalling doesn't occur.

DMFs don't like being engaged at engine idle speed. They like a few revs more, even if it's just 1000rpm. Was a massive problem in London about 15 years ago when London cabbies found out the hard way.
