set-by loop with Occupancy/Light objects and PLM

Greetings,

I am getting many "set_by loop detected" errors in my logs like the
following when motion or occupancy changes trigger a light to turn on
or off.  I am testing with the tip of the svn trunk.

05/26/09 11:06:01 PM BUG! set_by loop detected with these objects: $hall_lightx10, $light_hall

I believe the file fragments I have included below show that I am
using the abstract Item objects in a fairly straight forward way as
documented in the various library module perl code comments.

Things seem to be working mostly as desired other than these errors
being output to the log.  Are these messages considered normal when
using the occupancy, light, and motion item objects?  I have not yet
attempted to trace down the loop.  Does it matter that I am using a
PLM as my powerline interface?  (I noticed that it seems to be a bit
more specific in identifying the initiating object when light devices
change state than the documentation seems to imply; ie, Serial is not
used as the set_by object).

Thanks for whatever light anyone can shed on this.
