Spindump when editing a saved search

I have saved searches in my database. Selecting a search item, CTRL-click and select Edit… starts a spindump and high CPU activity.
DTPO ver 2.10
macOS 10.13.5-beta (17F70a)

Is this a global smart group in the sidebar or one in a database? Do you remember its conditions?

This might also be an issue of the macOS beta, therefore please launch Apple’s Activity Monitor application (see Applications > Utilities), choose the frozen DEVONthink in the list of processes, select the menu item View > Sample Process and send the result to cgrunenberg - at - devon-technologies.com. Thanks in advance!
