vlc listening on amule's port when closed #172

I noticed something strange (and very reproducible) on my system:

1. download multimedia in amule (amule listens on ip/port 0.0.0.0:XXXX)
2. use vlc to preview the file in amule
3. leave vlc open, close amule
4. now amule refuses to start as vlc is listening on the same ip/port (verified with netstat -plunt)

Any idea what's happening here?
