I think so, some weeks ago I fixed the problem that images did not
"know" about their parents, i.e. objects that use them, like
TextureChunks. Changing this introduced of course circles in the pointer
structure. The MaterialMergeGraphOp did not ignore parents fields and
therefore got caught in an infinite loop until the stack was exhausted.
I've fixed it, can you please try again?
Thanks,
Carsten
