V1.9.1: Strange messages for pages in sub-folders

Hi,

I’ve updated to 1.9.1 and since then, all pages in folders (not root)
have no report, when I click on a plus sign to see pages stats of a folder
I see strange things as that:

#0 Piwik_ErrorHandler(…) called at [/home/meteo/domains/meteoduquebec.com/public_html/piwik/tmp/templates_c/%%41^416^416F4DD8%%datatable_actions_subdatable.tpl.php:12]

#7 Piwik_FrontController->dispatch(…) called at [/home/meteo/domains/meteoduquebec.com/public_html/piwik/index.php:53]

All pages in root folder have no problem, stats displayed ok!

Have I done something wrong?

Thanks,
Jacques
