hi,

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
pygst.require("0.10")
import gst

pipeline = gst.Pipeline("mypipeline")

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

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

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

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)
pipeline.add(cutter)

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

source.link(convert)
convert.link(level)
level.link(cutter)
cutter.link(fakesink)


pipeline.set_state(gst.STATE_PLAYING)
r = raw_input()
pipeline.set_state(gst.STATE_READY)
*******************

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

NOTE:
-----
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.

Thank's for your work
