I tend to get this error when either purchasing from the AH or taking items from the mailbox.

Error in AdiBags:
Interface\addons\AdiBags\widgets\ContainerFrame.lua:997:AdiBagsSection4:SetPoint():AdiBagsSection3 is dependent on this -- details
[Error 000001481E3EAAB0]

I also have the Adibags - TSM addon for the filtering/grouping it provides if thats relevant.
