To reproduce my problem I have written a .h5 file using the following
lines:

import numarray as N
import tables
out =3D N.identity(749, typecode=3DN.Float)
HDF =3D tables.openFile("probe.h5", mode=3D"w", title=3D'test')
HDF.createArray(where=3D'/', name=3D'T', object=3Dout)
HDF.close()

I installed numarray-1.2.3 and pytables-0.9.1. Again, the generated
'probe.h5' gives strange results when viewed using h5dump. Is there
anyone else who can find the lines

...

0, 0,
      (175,769): 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, =

with the above example using h5dump?
