Error when loading the database in stag classify

We get the following error when loading the database:

The error appears when loading the classifier for the node 134676 Actinoplanes sp. SE50, which is a HDF5 group instead of a dataset. And there is a dataset under with id 110.
The issue is probably related to the name of the species: 134676 Actinoplanes sp. SE50/110.
I can reproduce the error if I add a "/" to the name in the taxonomy.

For now solved in e8a433d. When loading the taxonomy, we replace / with -.
