It's somewhere in rBd5572eacc595.

This will crash instantly:

WM_event_add_mousemove(but->active->window);

but somewhere else, if revert the line above, it still crashes when quit Blender (after scrolling popover).

I did not find any crashes when quitting Blender with my fix. Let me know if it's still there.
