Yes, I can reproduce this. The initial clone works fine, but later
"git fetch" quickly emits
fatal: bad object 0000000000000000000000000000000000000000
error: bzr::lp:upstart did not send all necessary objects
"GIT_TRACE=1 git fetch" tells me the command emitting that message
is "git rev-list --objects --stdin --not --all", called by
check_everything_connected(). Presumably the ref_map does not have
values filled in, though it should.
Tracing back further, the underlying cause *might* be the transport
machinery not coping well with remote helpers that do not know
what commit each remote ref points to. In response to the "list"
command they give
? refs/heads/master
? refs/tags/0.6.0-2
...
which gets translated into the ls-remote output
0000000000000000000000000000000000000000 refs/heads/master
0000000000000000000000000000000000000000 refs/tags/0.6.0-2
...
Thanks,
Jonathan
