Hello,

today I discovered that it's a bad idea to "git subtree pull" from an
annotated tag. This issue got discussed in those two threads:

http://comments.gmane.org/gmane.comp.version-control.git/247503
http://comments.gmane.org/gmane.comp.version-control.git/248395

I was under the impression that it is fixed in recent versions of git
but my homebrew 2.7.0 still behaves badly. If I run the attached script
to reproduce the issue I get the following error message:

> git push using:  sub somebranch
> fatal: 6d621d73ca18dc90424de0929357b5ae62988e00 is not a valid 'commit' object
> Can't copy commit ab38e3fe1ff27f7f87505db37d35adc5c3ceed27

> git ls-remote sub

> 99be40f8e3a4c926d45507be53ab6918789b3a52      refs/tags/sometag^{}

Besides handling this bug could you please give me a hint how to repair
my main repository? The problematic subtree pull happened some time ago
so I cannot alter the pull itself. I could go the brutal approach and
remove, then re-add the subtree but I guess there is a smarter approach.
Any help is appreciated!

Thanks,
Gregor
