cmd_add_commit() is passed FETCH_HEAD by cmd_add_repository, which is then rev-parsed into an object ID. However, if the user is fetching a tag rather than a branch HEAD, such as by executing: $ git subtree add -P oldGit https://github.com/git/git.git tags/v1.8.0 The object ID is a tag and is never peeled, and the git commit-tree call (line 561) slaps us in the face because it doesn't handle tag IDs. Because peeling a committish ID doesn't do anything if it's already a commit, fix by peeling[1] the object ID before assigning it to $rev, as per the patch.
