[Pytables-users] Problem with 0.5.1

[<ho...@gl...>]

We are need to read the PyTables generated HDF5 files to be read by
applications linked against HDF5 1.4.4, so we are still bound to
PyTables 0.5.1. But I now have as serious problem with a generated
file. Trying to read the dataset written by PyTables using a FORTRAN
application I get:

HDF5-DIAG: Error detected in HDF5 library version: 1.4.4 thread 0.  Back =

So from line 174 on something seems to go totally wrong. Has anyone an
idea what's going wrong here?
