No -- we never ran classicupgrade.
We created the original DCs with a custom package (that should be close, but not exactly the same as 4.0.6).
We then took a fresh 4.9 DC, joined it to the old domain, removed the old DCs and transferred the FSMO roles.
As our original DCs should be close to 4.0.6, I would think this bug doesn't quite apply as it was supposedly fixed by 4.0.1.
