I developp a program with pysgt/gtk: I have quite finished my project, but
encounetr a big memory leak problem: I reduced the program to find out where
ths happened. Here are the versions of the gstreamer and pygst packages. I'm
working on a etch/debian up to date machine: I to use the last pygst package,
just downloaded from the site today.

and the /gst-python-0.10.7

follows the smallest programwhich shows the problem:
#!/usr/bin/env python
# -*- coding: UTF8 -*-

import pygst
import gst

pipeline = gst.Pipeline("mypipeline")

source = gst.element_factory_make("alsasrc","audio")

convert = gst.element_factory_make("audioconvert","audioconvert")

level = gst.element_factory_make ("level", "level")
level.set_property('interval', 50000000)

cutter = gst.element_factory_make ("cutter", "cutter")
cutter.set_property("threshold-dB", -25.0)
cutter.set_property("run-length", 2000000000)
cutter.set_property("pre-length", 300000000 )
cutter.set_property("leaky", True)

fakesink = gst.element_factory_make ("fakesink", "fakesink")


r = raw_input()

il you launch the system monitor, you will see the resident part of memory
growing as fast as 1mo every 10 sec.

I added some tests from the time I sbmited the bug to berlios:

the problem arises when inserting the level plugin: when I lauch the pipeline
with gst-launch, no problem: with a small python prog, the resident part of
memory grows quickly.
