settlingFoam fails with timeVarying conditions on U

settlingFoam fails when a timeVarying boundary condition is used for the U field, since Vdj inherits the boundaryField from U, leading the code to a segmentation fault when
I'm not sure why Vdj inherits the BC's from V, since it is computed explicitly. However a workaround could be to replace the declaration of Vdj in createFields.H with (I left the commented line).
volVectorField Vdj ( IOobject ( "Vdj", runTime.timeName(), mesh, IOobject::NO_READ, IOobject::AUTO_WRITE ), mesh, dimensionedVector("0.0", U.dimensions(), vector::zero) //,U.boundaryField().types() );

The bug also exists for alpha BC, since Alpha inherits the boundaryField from alpha.
I tried a similar fix for this BC.
volScalarField Alpha ( IOobject ( "Alpha", runTime.timeName(), mesh, IOobject::NO_READ, IOobject::AUTO_WRITE ), alpha*rhod/rho //,alpha.boundaryField().types() );
But I get the next error message when trying to run the case:
volScalarField Alpha ( IOobject ( "Alpha", runTime.timeName(), mesh, IOobject::MUST_READ, IOobject::AUTO_WRITE ), mesh // alpha*rhod/rho //,alpha.boundaryField().types() );
It seems to work fine, but I had to manually calculate and create the Alpha bondaryField File in the 0 folder, and apply the timeVaryingUniformFixedValue to this BC instead of applying it to alpha.
P.S.: Note the difference between alpha and Alpha. Alpha= alpha*rhod/rho
