This bug is a favorite of mine. It has been reported on the mailing list 
before. It is also in the bug tracker:

http://public.kitware.com/Bug/view.php?id=10312&nbn=1#bugnotes 
<http://public.kitware.com/Bug/view.php?id=10312&nbn=1#bugnotes>

In each case a patch has been given to solve the problem. Nothing has 
happened, however.
