git log --no-walk --tags produces strange result for certain user

Hey,

I use the following commands to receive the list of tags together with hashes the point to:
  
    git log --tags --no-walk --format=%H%d%x01 --decorate=full

Generally it works fine, however a user reported that for his repository this command returns the list containing several hashes without tag references. Something like this:

    05c9a3a6247698ff740ca3a79828456347afdcef (HEAD, tag: refs/tags/2.33, refs/remotes/origin/master, refs/remotes/origin/HEAD, refs/heads/master)

    a7fda708d76d7f83d5a160b6b137b98b7677f771 (tag: refs/tags/2.44)
    f119c2e7c69bb5ed1da5bae29c8754550ab96bde

    07385a6ebe5a2e01e6ba9c8d0cb7b15c9a13f65d (tag: refs/tags/1.69)


Here third hash doesn't have a reference. There are 3 such hashes in his repository.

How can this happen? Is it a bug or some special scenario?

* I've already asked the user to execute `git tag --points-at` on these "suspiciously tagged" hashes: nothing was returned.
* `git show --decorate=full` executed on these hashes return commit details, and no references on them.
* From the log user sees that these hashes indicate some "normal" commits, nothing special at first glance.

Git version that he uses is 1.8.4.0.

Thanks!

Sorry for the duplication, but does anyone have an idea about this issue?

I'm worried because I've already received reports from 3 users, and I'm not sure if just skipping these "pseudo-tags" is a correct decision.

Thanks for any help!
