 P.S. If in the future you want to get more sensible error reports, then you
 should think about a few examples. People understand examples better than
 lengthy documentation descriptions.

Likewise a self-contained executable example makes diagnosing bug
reports considerably easier. As Andres said this is likely a caching
issue related to when changed settings take effect after making a
physical change.
