PHP Fatal error: Call to a member function toHtml() on a non-object in /var/www/w/includes/ImagePage.php on line 921 The request URL was: /wiki/File:Wikimedia_Community_Logo.svg Does not happen again when going to that URL, so it probably has to do something with caching.
Looks like this can happen if the transform call for the history line thumbnails fails. Should be checking the return value on it.
Done in r46691. ForeignApiRepo::transform() already returns false on failure, so I threw a quick check to do the same into File::transform(). ImagePage now checks to see if $thumbnail is false before calling toHtml().
