Hi, 
  Thanks for the reply,  I'm currently running python 2.6 but thats not the issue here (not to say it won't be an issue when I resolve this one :-))
 
it's the compiled silence.cpp file thats throwing up that error, I'm calling it directly form the command line and would expect it to show the usage information.

I've run it under strace and can see it's opening a socket with this call
	connect(3, {sa_family=AF_FILE, path="/var/run/dbus/system_bus_socket"}, 33) = 0
 but subsequent reads from the socket are failing like this
	read(3, 0xe7f6f0, 2048) = -1 EAGAIN (Resource temporarily unavailable)

The fifo file looks fine to me
	$ ll /var/run/dbus/system_bus_socket 
	srwxrwxrwx. 1 root root 0 Mar 12 11:53 /var/run/dbus/system_bus_socket

I've also tried setting selinux to permissive but that made no difference.

Thanks
  Russell
