+ * GLib-GObject-WARNING **: cannot register existing type `GstObject'
+
+ If you get this warning, this usually means your plugin or application
+ is linked against both libgstreamer-1.0.so and libgstreamer-0.10.so.
+ Make sure you have changed all -0.10 references in your configure.ac,
+ pkg-config invocations or Makefile.am/Makefile to -1.0.
+
+ While both versions can co-exist without problems on the same system, it
+ is not possible to use both versions at the same time in the same
+ application.
