It's 1.7.2.1.295.gdf931 on Debian testing. Which is pu as it was on midnight UTC (I build it from cron) + these patches (which shouldn't matter):

    # Monkeypatches

                  git cherry-pick 041bc904d2 # t/lib-git-svn.sh: use
$PERL_PATH for perl, not perl from $PATH
    git cherry-pick 855a1f8836 # commit: fix test broken by

    git revert --no-edit 48e46574e6 # rebase -i: add exec command to
launch a shell command

My shell is Debian /bin/dash 0.5.5.1-6.

Unfortunately the error with rebase was some one-off thing that I couldn't reproduce. I'm not even sure /what/ I did to make it happen.
