Please file a bug and attach the whole valgrind log. Please use valgind as below:

G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind --tool=memcheck
--leak-check=full --show-reachable=yes --log-file=valgrind.log gst-launch-0.10
udpsrc port=5000 caps="application/x-rtp,media=(string)audio,
clock-rate=(int)44100,channels=(int)2, payload=(int)96" ! gstrtpbin !
rtpL16depay ! audioconvert ! audioresample ! liveadder ! alsasink

Ideally use the gst.supp file from gstreamer git
http://cgit.freedesktop.org/gstreamer/common/tree/gst.supp
