Full script is uploaded to
https://dl.dropbox.com/u/10828740/rebase.log Here is the last page:

-----------------------------------[code]
if test -s "$dotest"/rewritten; then
    git notes copy --for-rewrite=rebase < "$dotest"/rewritten
    if test -x "$GIT_DIR"/hooks/post-rewrite; then
        "$GIT_DIR"/hooks/post-rewrite rebase < "$dotest"/rewritten
    fi
fi

rm -fr "$dotest"
git gc --auto
git rev-parse HEAD

ret=$?
test 0 != $ret -a -d "$state_dir" && write_basic_state
exit $ret

rebase -i fails with different error:

» git rebase -i master rebase_debug
