$NetBSD: patch-tracopt_versioncontrol_git_PyGIT.py,v 1.1 2014/03/11 17:41:44 gdt Exp $

The git browser can fail if the git log process has already exited when
trac tries to terminate it (resulting in a python exception).

This patch should be applied upstream; Reported to trac-devel@ on 2014-03-11.
