Stephen R. van den BergThe most likely cause for circular references are bad entries in the grafts file; since basically noone tells you where you went wrong, it can be a bit puzzling to find out that part of your tree goes dark sometimes, depending on which tool/options you pick to walk the commit-tree (most notably, things go wrong when using --topo-order even though things *seem* allright without that option).
