Week : teasers are shown in week calendar

In the week calendar view, the teasers are shown, which of course should not be the case.

The reason is simple, the following code is pasted at the bottom of event-node-week.tpl.php (without an if statement for example)

<div class="content description"><?php print $teaser ?></div>
  <div class="links"><?php print $links ?></div>
  <div class="links"><?php print $calendarsignup ?></div>
