It seems that gst_is_initialized() wasn't added until version 0.10.31.
And it just so happens that Ubuntu 10.10 has 0.10.30, so compilation
was failing.
/* Make sure GStreamer has been initialized if it hasn't been already;
in particular, if you want your program to parse GStreamer command line
options then you should do it yourself, before gtk_init(). */
- if( !gst_is_initialized() )

+ /* SUCKY DEBIAN: gst_is_initialized() supported from 0.10.30 onward */
+ /*if( !gst_is_initialized() )*/
gst_init(NULL, NULL);
