[Bug 1451028] Please test proposed package

[Robie Basak]

Hello Jens, or anyone else affected,

Accepted subversion into xenial-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/subversion/1.9.3-2ubuntu1.2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Title:
  git-svn coredumps

Status in subversion package in Ubuntu:
  Fix Released
Status in subversion source package in Xenial:
  Fix Committed
Status in subversion package in Debian:
  Fix Released

Bug description:
  [Impact]

  Subversion's Perl bindings randomly crash. This is most typically seen
  when using git-svn, since it's a heavy user of the bindings.

  [Test Case]

  "git svn clone -s svn://svn.code.sf.net/p/flightgear/fgaddon". With
  the existing package in xenial, git-svn kept crashing while trying to
  checkout the first revision. With the updated package, I've
  successfully processed 2400 revisions before being interrupted by a
  network issue.

  [Regression Potential]

  This brings the code up to date with current released Subversion code
  in this area. The upstream release which included these changes
  (1.9.5) has been in Debian since 2016-11-29 and I've received no
  further reports of issues.

  So right now git-svn seems to be useless on ubuntu 14.10 (Linux lubdev

  It seems to be related to
