metafont trouble with dpdfezzz

Hi,

just found out that `dvips -Ppdf' catch an error:

  werner/Tests> mktexpk --mfmode dpdfezzz --bdpi 8000 --mag 1+0/8000 --dpi 8000 tcrm1000
  mktexpk: Running mf-nowin -progname=mf \mode:=dpdfezzz; mag:=1+0/8000; nonstopmode; input tcrm1000
  This is METAFONT, Version 2.71828 (Web2C 7.5.4)
  ! Enormous number has been reduced.

                                    ; nonstopmode; input tcrm1000
  ? 
  ! Emergency stop.
  <*> \mode:=dpdfezzz; mag:=1+0/8000
                                    ; nonstopmode; input tcrm1000
  Transcript written on mfput.log.
  grep: tcrm1000.log: No such file or directory
  mktexpk: `mf-nowin -progname=mf \mode:=dpdfezzz; mag:=1+0/8000; nonstopmode; input tcrm1000' failed to make tcrm1000.8000pk.

A workaround would be a recalculation of the 0/8000 value, just like
done with

  werner/Tests> mktexpk --mfmode dpdfezzz --bdpi 8000 --mag '1+0/(4000*2)' --dpi 8000 tcrm1000

comments?
