WoWInterface - I Seem to Get an "Action Blocked" Error

Hi, I'm kind of new to reporting stuff like this so if I've missed anything, I'm sorry.

I was playing with nUI+ tonight and it seems that whenever I begin a new session (start up the game, log in) and start fighting I incur an interface error. It only occurs once and I seem to be okay for the rest of my play even if it's hours of play with instance runs and lots of questing etc.

I went ahead and turned on the taint log and this is what it produced:

Code:

3/30 23:58:13.664  Global variable NUM_BATTLEFIELDMAP_OVERLAYS tainted by nUI - Interface\AddOns\Blizzard_BattlefieldMinimap\Blizzard_BattlefieldMinimap.lua:166 BattlefieldMinimap_Update()

3/30 23:58:13.664      Interface\AddOns\Blizzard_BattlefieldMinimap\Blizzard_BattlefieldMinimap.lua:78 BattlefieldMinimap_OnEvent()

3/30 23:58:13.664      BattlefieldMinimap:OnEvent()

3/30 23:58:13.664  Execution tainted by nUI while reading NUM_BATTLEFIELDMAP_OVERLAYS - Interface\AddOns\Blizzard_BattlefieldMinimap\Blizzard_BattlefieldMinimap.lua:209 BattlefieldMinimap_Update()

3/30 23:58:13.664      Interface\AddOns\Blizzard_BattlefieldMinimap\Blizzard_BattlefieldMinimap.lua:78 BattlefieldMinimap_OnEvent()

3/30 23:58:13.664      BattlefieldMinimap:OnEvent()

3/30 23:58:13.664  An action was blocked in combat because of taint from nUI - nUI_TopLeftBar_Button8:Show()

3/30 23:58:13.664      Interface\FrameXML\ActionButton.lua:184 ActionButton_Update()

3/30 23:58:13.664      Interface\FrameXML\ActionButton.lua:339 ActionButton_OnEvent()

3/30 23:58:13.664      nUI_TopLeftBar_Button8:OnEvent()

Also, I was getting this error with the regular nUI but I never turned on the taint log so I don't know if it's the same.

Finally, I'm only running nUI as it's all I need, so there's no other AddOn interfering. :)
