RSC Error

[mOOwalker]

After a Battle Rez I got the following spamming error:

Code: [Select]

Message: Interface\AddOns\RaidSlackCheck\RaidSlackCheck.lua:553: Usage: UnitBuff("unit", [index] or ["name", "rank"][, "filter"])
Time: 03/21/13 22:42:14
Count: 449
Stack: [C]: ?
[C]: in function `UnitBuff'
Interface\AddOns\RaidSlackCheck\RaidSlackCheck.lua:553: in function `rsc_OnUpdate'
[string "*:OnUpdate"]:1: in function <[string "*:OnUpdate"]:1>

Locals:

There must be an lua error I hope I fixed it, but I don't know what happens :/ without an error, if it spam - it stops for some reason (error)
