Last r74971, updated standalone libs, latest FuBar v3.5.6, USEng client/server. Join a raid group and attempt to mouse over the FuBar icon to get the Tablet list of people with missing buffs. Following error is thrown up and repeats every time you mouse over it:
MoBuffs-1.3.1 (Build 74971)\\MoBuffs.lua:362: attempt to perform arithmetic on field '?'

This error also occurs in 5-man groups. Hope the author--who seems to be MIA--or someone else updates this for WotLK (the error, missing/changed spells, etc.) :).
This is probably my favorite implementation of simple raid buff checking among the overflow of buff checking mods on the SVN right now. A quick look in FuBar to see who isn't buffing, instead of having to type out commands/open up Waterfall or embarass people in party/raid/officer chat.
It has a problem though. Yes...it eats CPU time ;). It does so when you are idle and either solo or in a party/raid, which it shouldn't be doing. It may be the LibTalentQuery-1.0 library doing it, which the only required library for it that I have embedded; every other library I have standalone. Or it may be the mod. Regardless, it would be great if you could cut or eliminate the usage.
When idle, either in a raid or solo, it continually eats 0.105 CPU/sec median (measured with OptionHouse). Not total CPU, but ongoing consumption. RaidBuffStatus and FuBar_RaidBuffFu (the other two buff checkers I've recently installed) use 0 CPU when idle.
Its likely scanning for everyone's buffs all the time, in order to keep the results text updated (as you need to do nothing to see updated results). This is really not needed and may be why its eating CPU when idle. Change it to do a buff check only when you click the FuBar icon (or similar)? Or something else that will cut the idle usage.
