As per wiki/ReportingBugs, please specify which version you are running at both ends.
This looks like an outdated version on the server at least.

Resolution: invalid
Status: newclosed

Your server version is completely out of date, and full of security issues. Details here: wiki/Packaging/DistributionPackages.

Don't use the packages from Ubuntu, or if you do, report the bugs there (and nothing will happen since they have never applied a single fix in 4 years).
