It looks like git-update-index will not create $GIT_INDEX_FILE at all if you have no actual input lines to --index-info. So perhaps you have some commit in your repo that has no actual content in it. Either that or for some reason your "ls-files -s | gsed" invocation is producing no output.

Try adding a "touch $GIT_INDEX_FILE.new" at the beginning of your index filter and see if that helps. Then the file will always exist to be moved, even if we write nothing to it. If it works, then problem solved. If you get a repo full of empty commits, then something is wrong with your gsed pipeline.
