Annoying SMG error.

Whenever someone kills someone else with an SMG in my garrys mod, it spams this about 300 times in my console:
ERROR: GAMEMODE:‘HUDPaint’ Failed: includes/modules/killicon.lua:70: bad argument #1 to ‘GetTextSize’ (string expected, got nil)
I’ve tried alot of things like the killicon.lua in lua/includes/module, but that didnt work, and i’m really in need of a solution. Could anyone help me?

Delete killicon.lua

I know the problem

If you have this: http://www.garrysmod.org/downloads/?a=view&id=31609
