I see the same test fail randomly on Fedora (and I think on
CentOS/RHEL, but I run the full tests more often on Fedora).

For me, it's tests 3 and 4 which fail with the same error.
I thought it was a failure in subversion or the perl
bindings rather than git, so I simply disabled them in the
Fedora builds.  The Debian packages skip 9128 as well (and
9167, which fails similarly).

I've seen the failures in t9141 from 'git svn branch' as
well.  I made a note to re-enable those tests after Jeff's
work to make it easier to run with shell tracing enabled by
default, but have not done so yet.

The 'git svn' tests are not run in Travis because the perl
subversion bindings are not installed.  I haven't made time
to try installing them and running the tests in Travis to
see if the failures occur there, but I suspect they would.
