Gauss CoBlended scheme fails for div(phi,alpha) in interFoam

Summary

When using the scheme Gauss CoBlended for the term div(phi,alpha) in the solver interFoam, the simulation breaks up with the following error message: fvSchemes:

div(phi,alpha)      Gauss CoBlended 1. Minmod 2. upwind;

logfile output:

--> FOAM FATAL ERROR:
  Operator + is undefined for unoriented and oriented types

    From function Foam::orientedType Foam::operator+(const Foam::orientedType&, const Foam::orientedType&)
    in file orientedType/orientedType.C at line 458.

Steps to reproduce

Use tutorial /multiphase/RAS/interFoam/damBreak. Change in fvSchemes:

div(phi,alpha)      Gauss CoBlended 1. Minmod 2. upwind;

Run the case with Allrun.

Example case

The damBreak tutorial (tutorials/multiphase/RAS/damBreak)

What is the current bug behaviour?

Run fails in first alpha-Subcycle. Logfile output:

 Courant Number mean: 0 max: 0
  Interface Courant Number mean: 0 max: 0
  deltaT = 0.00119048
  Time = 0.00119048

  PIMPLE: iteration 1
  smoothSolver:  Solving for alpha.water, Initial residual = 0, Final residual = 0, No Iterations 0
  Phase-1 volume fraction = 0.130194  Min(alpha.water) = 0  Max(alpha.water) = 1


  --> FOAM FATAL ERROR:
  Operator + is undefined for unoriented and oriented types

    From function Foam::orientedType Foam::operator+(const Foam::orientedType&, const Foam::orientedType&)
    in file orientedType/orientedType.C at line 458.

What is the expected correct behavior?

Normal interFoam-running would be expected.
