Bug report: Fatal error: Declaration of Piwik_SearchEnginePosition_Filter_AddAveragePage::filter() must be compatible with that of Piwik_DataTable_Filter::filter()

I am getting the following error with SVN trunk:

Fatal error: Declaration of Piwik_SearchEnginePosition_Filter_AddAveragePage::filter() must be compatible with that of Piwik_DataTable_Filter::filter() in /var/www/plugins/SearchEnginePosition/Filter/AddAveragePage.php on line 18

To reproduce it go to Referrers => Search Engines & Keywords => Search Engines and click on an engine.

I still cannot report it to the trac page, so it goes here.
