Its just a performance issue, try this:

> GST_DEBUG="GST_REGISTRY:4" GST_DEBUG_NO_COLOR=1 gst-launch-0.10 2>debug.log fakesrc num-buffers=10 ! fakesink  fakesinkk
> grep "replacing" debug.log
0:00:01.053512375  4560  0x804f050 DEBUG         GST_REGISTRY
gstregistry.c:448:gst_registry_add_feature:<registry0> replacing existing
feature 0x80f1da0 (capsfilter)

...

Problem is that when a plugin is used, gstreamer calls plugin_init() and this
calls gst_element_register(). Now gst_element_register() should be a bit
smarter and just return, if the plugin feature is already registerd (or if we
are not updating the registry. Ideally we could query that in plugin_init() and
skip registering the features (e.g. having a gst_registry_is_updating()).
