Forwarded from: https://launchpad.net/distros/ubuntu/+source/loudmouth/+bug/64372 After loudmouth has connected to the server and sent the initial handshake, just when the reply is being received, connection_connect_cb is called with some strange arguments: connection_data->fd == 0 connection_data->connection == 0x1 condition == G_IO_OUT g_io_channel_unix_get_fd (source) still returns the correct fd. The actual crash happens when connection_data->connection is used as a pointer. The attached patch contains a work-around for the problem, but the actual cause is still to be fixed.
