           Summary: Use of GST_PLUGIN_DEFINE_STATIC results in a module
                    constructor
           Product: WebKit
           Version: 525+ (Nightly build)
          Platform: PC
               URL: http://bugzilla.gnome.org/show_bug.cgi?id=510547
        OS/Version: Linux
            Status: NEW
          Keywords: Gtk
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org

As mentioned at <http://bugzilla.gnome.org/show_bug.cgi?id=510547>,
VideoSinkGStreamer.cpp's use of GST_PLUGIN_DEFINE_STATIC results in a global
constructor being created that calls g_thread_init() before Epiphany's main()
is entered.  This results in a nasty diagnostic being emitted when Epiphany
goes on to call g_thread_init() itself.

In general we need to avoid these sorts of constructors as they add to startup
time of applications linking against WebKit, and introduce memory footprint
which may not be used until much later.  In this instance the side-effect is
more severe, but we should keep an eye out for other subtler instances of this
problem.
