Details

I have about 15000 items listed in the 'History' screen. When I select 'Forget about this site' on an item with many occurrences, this bug occurs consistently.

What happens next is a 1-2 core 100% usage accompanied with a memory usage increase that runs into the gigabytes. If I wait a while, sometimes, everything returns to normal and the proper occurrences are deleted from the history.

Version 66.0a1 on up-to-date Arch Linux.
