One interesting possibility is for the Earth-type planet to be orbiting the red dwarf and tidally locked to it, with the red dwarf providing most of the heat - with the red dwarf in turn being in orbit around the G-type star somewhat outside the Goldilocks zone of the G-type; maybe a distance corresponding to the middle of Sol's asteroid belt.
The orbit of the planet would be stable because to get any decent amount of heat out of the red dwarf, the orbit has to be close; WAG would be 2 million km.
It's also worth noting that photosynthesis would probably rely heavily on the G-type sunlight; deep red and infrared light aren't all that good at breaking chemical bonds.
