Help me decipher this LUA error.

[tobindax]

I know WoW is terrible at specifying the addon that caused anything so I'd like the help of experienced coders (PS All the 3 addons (or more) mentioned in the error I can not do without so I wonder which one specifically caused it (it comes up on log on or shortly after)).
