Ah, I see, so these objects are _before_ fast-export tries to do
anything, it's just importing the marks without any knowledge if these
objects are going to be used in the export or not.

If that's the case, I don't think it should throw a warning even just skip them.

Then, in the actual export if some of these objects are referenced the
export would fail anyway (but they won't).

Cheers.
