Invalid product vars at line 106 in file classes/Link.php

Hello,
today I received a following error:

 

 

Invalid product vars
at line 106 in file classes/Link.php

 

and presta debugger shown me code like this:
 

<h5 class="s_title_block"><a href="<?php echo $_smarty_tpl->tpl_vars['link']->value->getProductLink($_smarty_tpl->tpl_vars['p']->value['id_product'],$_smarty_tpl->tpl_vars['p']->value['link_rewrite']);?>

Could anybody help me with that? That make me angry, because I got sometimes 500 error.
