Exclamation Mixing Plane + Ideal Gas Density (Compressible) = Tragedy

I am modelling a turbine stage comprising of a stator followed by a rotor using the mixing plane model. When I assign the material density as Ideal Gas instead of the default 'constant', I get a floating point error after 4-20 iterations depending on how I tweak the other boundary conditions.
Any assistance in this matter would be appreciated. Although I have seen many users facing this issue, I haven't yet found a working solution.
