Spotlight crashes after typing a few letters since Safari 12 update

Sierra 10.12.6

So this just started happening after updating to Safari 12 a few days ago.

When I invoke Spotlight, from Finder (command-spacebar) or from menubar, and type a few letters. It immediately vanishes because it crashes.

I forced Spotlight to re-index several times and it briefly works until the indexing is done and then the problem returns. It also happens while using a different Admin account. After a lot of troubleshooting, I can get it to stop crashing by only UN-checking the "Bookmarks & History" option in the Spotlight pane of System Preferences (all other Spotlight options are checked). I think it's a bug or issue with Safari since it's only "Bookmarks & History" and the problem coincides with the update to version 12.

This problem is 100% repeatable.

Here is a portion of the crash log. I can provide more of this log upon request.
