           Summary: Server can be crashed by sending commands to zombies
           Product: ioquake3
           Version: SVN HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P3
         Component: Misc
        AssignedTo: zakk at icculus.org
        ReportedBy: andi.christ at gmx.net
         QAContact: quake3-bugzilla at icculus.org


To reproduce the crash:
- run a server with ten bots
- during intermission do /kick all

Every disconnecting client then sends a scores command to everyone, so the last
bots to leave will get a lot of those. The server will crash with the message
"netchan queue is not properly initialized in SV_Netchan_TransmitNextFragment".

One way to prevent this is to exclude zombie clients in SV_SendClientMessages,
but that may have side effects.
