1.5.6.5 fails to clone git.kernel.org/[...]/rostedt/linux-2.6-rt

I have git 1.5.6.5 installed from the Debian/lenny package.

Poking around in http://git.kernel.org/ looking for a git repository that might have the latest -rt development happening, I found

  http://git.kernel.org/?p=linux/kernel/git/rostedt/linux-2.6-rt.git

which looked promising.

But when I tried cloning it using:

    git clone rsync://rsync.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-rt.git linux-2.6-rt

it pulled several hundred megabytes through my (rather slow) DSL line and then printed out

  error: Trying to write ref refs/tags/v2.6.11 with nonexistant object 5dc01c595e6c6ec9ccda4f6f69c131c0dd945f8c
  fatal: Cannot update the ref 'refs/tags/v2.6.11'.

and then removed everything it had just pulled.

Looking at http://git.kernel.org/?p=linux/kernel/git/rostedt/linux-2.6-rt.git;a=tags I see that apparently v2.6.11 and v.2.6.11-tree both point at a tree object and not a commit.

Is this a bug in git? (Even if there is something wrong with the git repository I was trying to clone, the fact that it removed all the work that took a long time to pull is annoying.)

Is this problem already fixed in some newer version of git?
