In file eztemplatesstatisticsreporter.php the edit tool paths miss the leading / , making them relative. Thus they dont work when on any subpage of the site.

To reproduce, set "Debug output" and "List of used templates" on on
http://demo.ezpublish.no/corporate_admin/
and then go to
http://demo.ezpublish.no/corporate/galleries/landscape

Hover over edit icon, note that path includes "/galleries/"

Fix: set as follows:
$templateViewFunction = '/visual/templateview/';
$templateEditFunction = '/visual/templateedit/';
$templateOverrideFunction = '/visual/templatecreate/';
