Do you have the reproduction steps for this? If I run

  git -c protocol.version=2 fetch --tags \
    https://chromium.googlesource.com/chromium/src \
    +refs/heads/*:refs/remotes/origin/* --depth=1

repeatedly in the same repository, it succeeds. (And I've checked with GIT_TRACE_PACKET that it uses protocol v2.)
