I have that error in WoW Cata with TukUI.
Every time I close the options window this error pops up:
Message: ...erface\AddOns\VuhDoOptions\VuhDoPanelConfigTools.lua:166: table index is nil

I played around with the options and everything seems to work.
I have successfully healed a 5man dungeon with VuhDo
