Right here on the mailing list is fine.

If it's definitely a bug, you could also open a bug report in our bug tracker:
http://public.kitware.com/Bug

As usual, with all bug trackers, you should search for an existing
report that describes the issue before submitting a new one. You can
monitor the existing issue to be updated by email when it is fixed.
