/changeset/trunk,16 is not a valid link to a changeset. I think /changeset/16/trunk was meant. This sounds like a PluginIssue, as such a link should never be generated by Trac. Please report the issue to the plugin maintainer, or reopen this ticket if you can reproduce the issue without any plugins.

Right, it looks like this was generated by the trac-bzr plugin.
