Dem woes: Unexpected Type-3 record encountered

[NSF SF Bay research projects]

I have been trying to use the m.dem.extract tool to
convert to grass 1-degree dem files available on the
net.  (These are files -- not tape info.) However, I get
the error message described above.  Is there an easy
fix?

(I realize that I could edit the (ASCII) dem files
with sed to remove header-type info, import these into
grass as raw ASCII raster files, then convert from a
radial projection to UTM, but this is looking like a
hassel.)

Any, any help would be appreciated.
