            Bug ID: 146707
           Summary: [GTK] The "Missing Plug-in" buttons are not showing up
                    on some flash contents

           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk

the test content taken from http://www.youku.com/

Currently, WebKitGTK+ doesn't show the "Missing Plug-in" buttons if the plugin-related tags don't have a "type" attribute.
In such a case, WebCore tries to guess the MIME type from the extensions by using MIMETypeRegistry::getMIMETypeForExtension().
For WebKitGTK+, MIMETypeRegistry::getMIMETypeForExtension() goes through |extensionMap|, which is a simple array of
<extension, mime type>, looking for the mime type for the given extension. But |extensionMap| in MIMETypeRegistryGtk.cpp
doesn't have the information for ".swf", so WebCore fails to guess the MIME type and regard the content type as
ObjectContentFrame, not ObjectContentNetscapePlugin.
