nautilus --check stuck after nautilus_self_check_directory

According to
  nautilus --help
there is an option
  -c, --check Perform a quick set of self-check tests.

Running 'nautilus --check' on the 19.10 beta or on 18.04.3 prints:
  running nautilus_self_check_file_utilities
  running nautilus_self_check_file_operations
  running nautilus_self_check_directory

And then it just sits there. This is probably not intended.
