appsrc example not works with 1.0.10 on Linux ?

[comicfans44]

Hello 
     I'm trying appsrc example ,but found the code from document 
(http://gstreamer.freedesktop.org/data/doc/gstreamer/1.0/manual/html/section-data-spoof.html) 
not works on Linux (with gstreamer 1.0.10),GST_DEBUG=3 gives 
0:00:01.446809539 30432  0x8055660 FIXME                default gstutils.c:3636:gst_pad_create_stream_id_printf_valist: Creating random stream-id, consider implementing a deterministic way of creating a stream-id

but same code on windows (http://gstreamer.freedesktop.org/data/pkg/windows/1.0.10/) with misc code change (xvimagesink -> autovideosink) just works,
anyway, similar example works with 0.10 on both windows and Linux , is this a 1.0 bug ?
