After today's Pre Launch patch, 11/15, I'm getting the following error on the evoker.

5x Interface/AddOns/IcyVeinsStatPriority/Data.lua:178: bad argument #1 to 'gsub' (string expected, got nil)
[string "=[C]"]: in function gsub' [string "@Interface/AddOns/IcyVeinsStatPriority/Data.lua"]:178: in function <Interface/AddOns/IcyVeinsStatPriority/Data.lua:176> [string "@Interface/AddOns/IcyVeinsStatPriority/Data.lua"]:211: in function GetSPText'
[string "@Interface/AddOns/IcyVeinsStatPriority/Core.lua"]:759: in function `?'
[string "@Interface/AddOns/IcyVeinsStatPriority/Core.lua"]:718: in function <Interface/AddOns/IcyVeinsStatPriority/Core.lua:717>

Locals:
(*temporary) = nil
(*temporary) = "Haste"
(*temporary) = "Haste"
(*temporary) = "string expected, got nil"

Fixed.
