The WebView updates settings via "notify" signals from WebSettings and tests the property name for a known string, otherwise it emits a warning. This results in wrong warnings if WebSettings is subclassed in an application and assigned to a WebView. Current git versions of midori will trigger this wrong behavior because MidoriWebSettings has a number of additional properties which the WebView doesn't know about.
Created attachment 20782 [details] Check for valid properties This patch lets the WebView check if the property is valid even if it doesn't know about it, and only if that is not the case emits a warning.
