git-describe doesn't show the most recent tag

Hi,

I'm trying to run git-describe on the open-iscsi git tree (git://git.kernel.org/pub/scm/linux/kernel/git/mnc/open-iscsi.git):

[erez.zilber@erez-lx:/tmp/open-iscsi.git]$ git-branch -a
* master
  origin/2.0-869-bugfix
  origin/HEAD
  origin/bnx2i
  origin/cxgb3i
  origin/master
[erez.zilber@erez-lx:/tmp/open-iscsi.git]$ git-describe
2.0-868-rc1-81-g31c9d42

However, there are newer tags than 2.0-868-rc1: [erez.zilber@erez-lx:/tmp/open-iscsi.git]$ git-tag 2.0-868-rc1 2.0-869 2.0-869-rc2 2.0-869-rc3 2.0-869-rc4 2.0-869.1 2.0-869.2 2.0-870-rc1

tag that is reachable from a commit". In this repository, it doesn't look like that...

Now, I switch to the "2.0-869-bugfix" branch: [erez.zilber@erez-lx:/tmp/open-iscsi.git]$ git-checkout -b 2.0-869-bugfix origin/2.0-869-bugfix Branch 2.0-869-bugfix set up to track remote branch refs/remotes/origin/2.0-869-bugfix. Switched to a new branch "2.0-869-bugfix"

and running again git-describe: [erez.zilber@erez-lx:/tmp/open-iscsi.git]$ git-describe 2.0-868-rc1-33-g81133dd

Only if I use the --tags flag, I get what I expected: [erez.zilber@erez-lx:/tmp/open-iscsi.git]$ git-describe --tags 2.0-869.2

Why is this happening?

Thanks, Erez
