WARNING: Sub-Space-Matrix is not hermitian in DAV in VASP 5.2

[SchrodingersCat]

I recently upgraded to VASP 5.2 from 4.6. I was retrying my bulk Magnetite (Fe3O4) calculation to see how different the energies were when I found the message: WARNING: Sub-Space-Matrix is not hermitian in DAV. What is strange is that I did not see this message when running the same calculation in VASP 4.6.

Was this warning added in VASP 5.2? Also, I have a suspicion that this may have something to do with the installation, specifically LAPACK/SCALAPACK.

Has anyone else had this experience?
