Product: GStreamer
Component: gst-plugins-bad 
Version: 0.10.5-4
OS: Debian GNU/Linux lenny/sid
Plugin: interleave
Element: interleave

Description: I just can't request new sinks from interleave without trouble.
It always tells me: GStreamer-CRITICAL **: Padname sink%d is not unique in element 


I made this small pygst program that reproduces the bug.

<--------------------------- bug.py -------------------------------->

#!/usr/bin/env python

# plugin: GStreamer plugins-bad - interleave-plugin
# bug: request sink bad doesn't work

import pygst
pygst.require("0.10")
import gst

# request pads works

adder = gst.element_factory_make("adder", "adder0")

print 'trying to request sinks from adder'

adder_sink0 = adder.get_request_pad("sink%d")
print 'adder_sink0: ok'

adder_sink1 = adder.get_request_pad("sink%d")
print 'adder_sink1: ok'



# request pads doesn't work (bug?)

interleave = gst.element_factory_make("interleave", "interleave0")

print 'trying to request sinks from interleave'

interleave_sink0 = interleave.get_request_pad("sink%d")
print 'interleave_sink0: ok'

# this will print:
#  GStreamer-CRITICAL **: Padname sink%d is not unique in element interleave0, not adding
interleave_sink1 = interleave.get_request_pad("sink%d")
print 'interleave_sink1: error should read above this line'

<----------------------------- output of the program ---------------------->
