I have cause to believe that recently crashes I have experienced when attempting to make use of the print menu in opera-12.16_6 can be traced to libproxy-0.4.15. Please see: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=238413 for further details, including a post-crash stack trace.
Opera is no longer in tree (repo) as of SVN r563988 so we can safely close this PR
