Hi,
I started to look at that bug and exchanged all deprecated HDF functions 
from octave code, but I cannot properly test/finish it and put into a 
proper patch for the next few weeks. Anyway, it seems that it doesn't 
help in reading the hdf file in question (though I could be wrong), but 
I presume that the "compound data" type which is used in there is not 
implemented in the octave routines.
