Source notes
Deutsche Kinemathek - Museum für Film und Fernsehen

Alexander Thelen is absolutely correct, although the film was released in January 1908. A description (in French) and review of the film (in English) can be found on the Fondation Jérôme Seydoux-Pathé website.

The Deutsche Kinemathek; Berlin, holds also a well preserved nitrate print (126 m) in b/w with German titles in red.
The German distribution title was DAS DURCHGEGANGENE PFERD:

This is definately "Le cheval emballé" from 1907, made by Pathé Freres. There's quite a lot of texts and other information on the internet.
