i've got a few files (this one has dvd subtitles) that will freeze our dreambox
after a few minutes because gstreamer consumes the entire memory.

i couldn't really reproduce the problem on the pc until i forced audio and
video sink to be fakesinks but then it munches about 1 mb/s on the pc aswell

gst-launch-0.10 playbin2
uri=file:///net/media/Videos/HD/The.Best.Exotic.Marigold.Hotel.mkv
text-sink="fakesink" video-sink="fakesink" audio-sink="fakesink"

when i disable the subtitles with the flags property, then there is no memory
leak

gst-launch-0.10 playbin2
uri=file:///net/media/Videos/HD/The.Best.Exotic.Marigold.Hotel.mkv
text-sink="fakesink" video-sink="fakesink" audio-sink="fakesink" flags=3

happens with 0.10.36 release and current git
