utf-8 filename woes

Hi,

  I have a git version 1.7.1 running on Scientific Linux 6.
When a filename with UTF-8 is present in a tree-ish the
"git archive" command crashes:

Installing the git-debuginfo package gave no additional information. The symptom does not show on a Fedora 21 system with git 2.1.0 (and I note that gitk properly shows those filenames on f21, and does not on sl6).

Is this a known and fixed issue, or something my sl6 system needs installing?
