I got the following error when I tried to view the history of a lvl 1 character who was initially blocked.
Error occured in: Global
Count: infinite (atleast it looked like the infinite sign, but copy & pasting it here makes it look like "8")
Message: ..\AddOns\WIM\Modules\Filters.lua line 832:
attempt to index field 'parentWindow' (a nil value)
Debug:
[C]: ?

At the time I got the whisper I remember clicking "view message" and responding.
I attached a little picture of how the WIM History looked like when the error popped. When the error occured the History Viewer froze and I was unable to use it until I did a reload of the interface.
