Re: dxtbx pytest issue

[PICCA Frederic-Emmanuel <frederic-emmanuel.picca@synchrotron-soleil.fr>]

For the record, I found it..., the upstream modify the HDF5_PLUGIN_PATH when loading the dxtbx module.

they guess that they are using conda and override the path. All this is useless on Debian since the plugin are system installed properly.

Cheers

# Ensures that HDF5 has the conda_base plugin path configured.

else:
