UI error from some addon - happen on opening container from inventory

Hello,

Im occasionally getting this error probably generated by some addon. Its fixed by reloading ui and appears occasionaly so its hard to track down which Addon causes it (by trying to disable one and check if happens again)

The error is:
"EsoUI/Ingame/Inventory/InventorySlot.lua:925: attempt to access a private function 'UseItem' from insecure code
stack traceback:
EsoUI/Ingame/Inventory/InventorySlot.lua:925: in function 'TryUseItem'
EsoUI/Ingame/Inventory/InventorySlot.lua:1148: in function 'OnSelect'
EsoUI/Libraries/ZO_ContextMenus/ZO_ContextMenus.lua:412: in function 'ZO_Menu_ClickItem'
8371350907706105899:4: in function '(main chunk)'
"
and it happens when trying to open container (like Naedic coffer, writ case/satchel/crate/coffer)

The mystery behind this error has already been solved a while ago.
It is caused by any addon that adds a context menu entry before the ingame ui can populate the context menu first.
It will be fixed in a future patch of the game, but until then you best watch out that you always open one of the built-in context menus after you log in with a character (e.g. right click on a quest in the journal).
