ISTR that older versions of PCB would create Gerbers with this error
if you tried to create a hole with zero diameter.  This bug was fixed
about a year ago, but if you're using an older version of PCB, then
you could encounter this problem.

Did you create a zero diameter hole in your design for any reason?
