As we discussed downthread, I tend to agree with you here that this
is a corrupt repository leading the tool to do a nonsensical thing,
and the true bug here is that "fsck" is not catching it.  But I do
not mind if we add a check at runtime, probably at the location the
patch under discussion identified, that makes sure a symbolic ref
points at a valid target the same way "git fsck" does.

Thanks.
