No, PyTables is meant to use the 1.6 API, even if you are using HDF5
1.8.x. So the line above is definitely correct.

PyTables does not support the HDF5 1.8 *API* at all, so I'm confused
here. But if your later approach works, and test passes, then go for it
(although I'd like to know what's happening in your setup).
