I installed on my centos 5.2 system via yum the soundconverter program to convert sound files.

when I open it from the gui it just flashes for a moment then closes. from the command line it again flashes for a second on the gui and gives this output in the terminal...

soundconverter
SoundConverter 1.4.0
using Gstreamer version: 0.10.9, Python binding version: 0.10.7

I have done a full yum update -y
I also have done an rpm -V which shows no output plus I have reinstalled it and rebooted

thanks in advance.
