segfault when different user

[Hoggins!]

Hello everyone,

I have a problem when launching Gstreamer from command line : when run
as root, everything is fine, it works as expected. If I log as a simple
user, and then launch the comand; I get a segfault. On the other hand,
if I log as root, and then "su" into the simple user, the command is
successfuly executed.

I suspect a problem within $PATH or user rights, but I can't see what it
can be.

The command :

nice --19 gst-launch gstrtpbin name=rtpbin latency=0 ! jackaudiosrc
connect=none client-name="sortie_streaming" latency-time=100
buffer-time=100 ! audioconvert ! celtenc bitrate=128000 complexity=0 !
rtpceltpay ssrc=10 ! udpsink qos-dscp=46 clients="10.2.1.1:5000"

    Thanks in advance for any hint on this.

        Hoggins!
