Mainly get first notice of interface failure in case of add-on then I join combat but it may happen any time tho.
Check my taint log: http://rapidshare.com/files/74116863/taint.zip.html
It's quite big but it all I get for around 5 hours of solo fram +raiding.
Tain log of Census bugs
Getting a little taint myself, although mixed up with other mods so can't blame Census for the problems I'm having (pretty sure it's mainly the other mods
) Copying and pasting a snippet in case it's any help in tracking the problem down though:
12/3 17:31:41.812 Global variable FriendsFrame_Update tainted by CensusPlus - Interface\AddOns\CensusPlus\CensusPlus.lua:625 CensusPlus_OnLoad()
12/3 17:31:41.812 CensusPlus:OnLoad()
12/3 17:31:41.812 Execution tainted by CensusPlus while reading FriendsFrame_Update - Interface\FrameXML\FriendsFrame.lua:750 FriendsFrame_OnEvent()
12/3 17:31:41.812 FriendsFrame:OnEvent()
12/3 17:31:41.812 An action was blocked in combat because of taint from CensusPlus - RaidFrame:Hide()

12/3 17:31:41.812 FriendsFrame:OnEvent()
...and that repeats over and over. Does Censusplus have any interactions with the raidframes? If not I'll blame the raidframe part on CTRA as the amount of taintspam I have from that has to be seen to be believed... CT seriously need to update their mods

Yeah I already use Grid, just keep CTRA for the various other features, mainly MT targets - plus I don't know if you can set MT targets in other addons, which is kinda needed as I'm often helping to run the raids I do. CT is kinda bugging me overall tbh, I may just look for replacements for the few functions I still use, getting sick of bugs from their mods 

Hmm, I really don't want to install other addons just to get at UIs for other addons... the more addons I run the more potential for problems (such as the enormous taintlogs I'm getting currently, plus petbars never ever showing when I dismount in combat) so I try to keep to a bare minimum.
Anyways at least Census doesn't seem to be causing me issues, whatever it's blocking isn't something I'm noticing
I did have an interesting occurance one time where I was looking at the raid pane on the social window and switched to the friendslist whilst in combat, and ended up with a horrible hybrid of the two stamped on top of each other that wouldn't go away until I got out of combat, but that might've been anything that caused it, just mentioning it because of the connection between Census and the friendslist in my taintlog

Clip from a taint log from today, with only Censusplus and KF running, so no intereactions with other mods:
