I can get the fetch to work, by removing refs/original in the source repo:

    This commit was manufactured by cvs2svn to create tag 'releases/3_2_0-5'.
...

Note that the object was present all along!

(In old_repo I had done: git filter-branch --prune-empty -- --all)

I have a backup of the repo, and this is repeatable for me, is there an odd interaction between fetch and refs/original?

Cheers, James
