Bug#657790: prboom: crash two players with server

[yellow]

Package: prboom
Version: 2:2.5.0+dfsg1-5
Severity: normal

Hi,

On a single machine, if I do : 

 prboom-game-server
and twice:  prboom  -iwad /usr/share/games/freedoom/freedm.wad -net 192.168.1.2:5030
it works

however, lets take now two machines on the intranet that can see all ports of each other

 prboom-game-server
Listening on port 5030, waiting for 2 players
Join by  (channel 0) as player 0
Player states: [r   ]
Join by  (channel 1) as player 1
All players ready, now confirming.
All players joined, beginning game.
