This broke git send-email for me.  The error message is

  Can't locate object method "starttls" via package "Net::SMTP" at /usr/lib/git-core/git-send-email line 1410.

Is 1.28 the right minimum version?

  $ perl -e 'require Net::SMTP; print version->parse($Net::SMTP::VERSION); print "\n"'
  2.31
  $ grep VERSION /usr/share/perl/5.18.2/Net/SMTP.pm
  use vars qw($VERSION @ISA);
  $VERSION = "2.31";
  $ grep starttls /usr/share/perl/5.18.2/Net/SMTP.pm
  $ dpkg-query -W perl
  perl    5.18.2-2ubuntu1.1

Patch left unsnipped for reference.

Thanks,
Jonathan
