"quasselcore -h|--help" tries to start quasselcore instead of just displaying the help message
The following is displayed after the help message.
2008-09-21 23:22:53 Info: Storage Backend is ready. Quassel Schema Version: 11
2008-09-21 23:22:53 Error: Could not open GUI client port 4242: The bound address is already in use
Just out of curiosity I tried to use a port which is not already used and I got the following.
quasselcore --port=3000 --help
2008-09-21 23:30:51 Info: Storage Backend is ready. Quassel Schema Version: 11
2008-09-21 23:30:51 Info: Listening for GUI clients on IPv6 port 3000 using protocol version 5
The strange thing is I can not find an additional process of quasselcore running at port 3000. So it is not really starting or dies immediately after issuing the command.
