[gst-devel] thread problem

[YuRiX]

hi *,
this is my first message to this list.
my dear gurus, i've this problem : i 've just followed the manual to
write a stupid program saving an audio stream from the internet,
splitting each song in a file. the first release works prettly, but 
when i've try to implement this functionality in multithreading fashion,
i get out this message:
(process:2325): GStreamer-WARNING **: bin "bin" is not the managing bin,
can't be iterated on!

this message appears also running the example code in chap 15 of the
manual.
is there something i'm missing ?
is it a know bug/feature?
or simply, is not the manual updated?

hoping to have post an usefull question
ciao
