3x [ADDON_ACTION_BLOCKED] AddOn 'omnibar' tried to call the protected function 'MultiBarBottomLeft:ShowBase()'.
[string "@!BugGrabber/BugGrabber.lua"]:480: in function <!BugGrabber/BugGrabber.lua:480>
[string "=[C]"]: in function ShowBase' [string "@FrameXML/ActionBar.lua"]:368: in function UpdateVisibility'
[string "@FrameXML/ActionBar.lua"]:331: in function ShowOverride' [string "@FrameXML/ActionBar.lua"]:321: in function SetShown'
[string "@FrameXML/MultiActionBars.lua"]:64: in function <FrameXML/MultiActionBars.lua:62>
[string "@FrameXML/MultiActionBars.lua"]:76: in function MultiActionBar_Update' [string "@FrameXML/ActionBarController.lua"]:216: in function ValidateActionBarTransition'
[string "@FrameXML/ActionBarController.lua"]:162: in function `ActionBarController_UpdateAll'
[string "@FrameXML/ActionBarController.lua"]:66: in function <FrameXML/ActionBarController.lua:55>

Not sure why this is happening now.
I looked at my taint log, can't root cause how Omnibar is interacting with action bar code.
