In the ezpublish-legacy component, the file lib/eztemplate/classes/eztemplatemultipassparser.php has a nonexisting variable called on line 184, causing an error when generating the parser error report.

I could trigger the error only by having an

tag closed by a '=' instead of a '}' at the end of a .tpl template.

I created a pull request on the github project : https://github.com/ezsystems/ezpublish-legacy/pull/1299
