SV_BotFreeClient: bad clientNum: 33550916

[Hindenburg]

I tried to run the risujin balance mod on my a local game on my linux to see what was new, and this is what I saw when I tried to start the game:

SV_BotFreeClient: bad clientNum: 33550916

What does this mean exactly? How do I correct it?
I got this file:

balance-svn879-17b.pk3

from here:

http://pub.risujin.org/tremulous/balance/

It runs just fine when I don't try to use the mod, but I get the error when I try to use it. Please explain.

your client's built in server is incompatible with the mod. this is one of several clients that should work with it.
