Closing this report as it has not been able to be reproduced
in the current code base. If it can later be reproduced we
can re-open and re-visit this issue...

I'm checking on this as well as I have both Debian 2.2 and
3.0 available in my home environment for testing... I don't
believe I've seen this with the current CVS version in my
testing thus far but I'll go back and look again...

Have you tried the CVS version - a few changes were made
recently.
