Extension talk:PicLens

I am not able to get this extension working. My wiki is version 1.12. On Special:SpecialPages the PicLens specialpage hast this link:

<a href=".../index.php/Spezial:PicLens" title="Spezial:PicLens">&lt;piclens&gt;</a>

and it looks so: <piclens>. If I click on this specialpage I get this errormessege:

Fatal error: Call to a member function exists() on a non-object in ...\extensions\PicLens\PicLens.body.php on line 28
