Problems since new patch came out

[colista]

I've recently been having LUA error's popping up since the recent patch tuesday 4/26/2011. I use spartanui - with oUF, love the target frames, but I run druid and a shammy and everytime I shapeshift, or pop treants i get this error. Can anyone give me any ideas on how to fix the problem? I really want to keep oUF
