svn-import failures with CommittedQueue error on CentOS 7

[khb]

With a new start (restored VM, reinstalled) I was unable to duplicate 1521415. However, I did stumble into a different hole

bzr svn-import https://sc01.profitool.com/svn/profitool/branches/source/bb

                   changed since the last import.
  --all Convert all revisions, even those not in current branch
                   history.
  --layout=ARG Repository layout (none, trunk, etc). Default: auto.
  -v, --verbose Display more information.
  --format=ARG Specify a format for this repository. See "bzr help
                   formats" for details. Must support rich-root.
  --standalone Create standalone branches.
  -q, --quiet Only display errors and warnings.

subvertpy no longer provixes subvertpy.wc with newer versions of Subversion (>= 1.7), as the Subversion working copy library has been rewritten with differences in behaviour.

You either need a version of Subversion older than 1.7 (and rebuild subvertpy against that) or update subvertpy to support newer versions of Subversion (which is a non-trivial task). See bug #887749
