>Description:
Summary is a bit misleading, but I can't quite cram the description of
the problem into one sentence.

What you need is

1) an svn client machine that only has IPv4 connectivity
2) an svn server with certificate that cannot be validated by default
3) an svn server that has both IPv4 and IPv6 addresses

>How-To-Repeat:
On a machine without IPv6 connectivity try:

  $ svn info https://svn0.ru.FreeBSD.org/base/head
  svn: E000065: Unable to connect to a repository at URL 'https://svn0.ru.freebsd.org/base/head'
  svn: E000065: Error running context: No route to host

I do see IPv4 connection attempt.  It's successful as a TCP
connection, but fails as HTTPS because server certificate cannot be validated (Issuer: clusteradm, FreeBSD.org, CA, US)

E.g. trying that svn info with explicit IPv4 address
of svn0.ru.freebsd.org:

  $ svn info https://77.88.40.110/base/head
  Error validating server certificate for 'https://77.88.40.110:443':
  ...

The svn version is:

  $ svn --version
  svn, version 1.8.10 (r1615264)
     compiled Oct 21 2014, 01:45:37 on powerpc--netbsd
