The operator "attribute(show, [level])" is used to show the content of an object. If the level / depth of showing content is to high you get an fatal error.

If you use the operator e.g.

{$node|attribute(show,10)}

in pagelayout.tpl

you get an fatal error:

Fatal error: Call to a member function on a non-object in C:\workspace\est\kernel\classes\ezcontentobjectattribute.php on line 394
Fatal error: eZ publish did not finish its request

The execution of eZ publish was abruptly ended, the debug output is present below.

Steps to reproduce

• insert {$node|attribute(show,10)} into pagelayout.tpl
• access the webpage
  => you get the error if not try a bigger number
