[LaurensRietveld]

I'm getting the following error in redmine 4.0.0 when somebody is mentioned (and the send-email is triggered):

ActionView::Template::Error (undefined method `default_url_options' for ActionMailer::Parameterized::Mailer:Class):
    1: <h4><%= link_to "[#{@issue.project.name} - #{@issue.tracker.name} ##{@issue.id}] #{@issue.subject}", issue_url(@issue) %></h4>
    2: 
    3: <br /><br />
