FileNotFoundError when importing with -Structure from file- using workflow executor

When the workflow executor is employed the default "evaluate none" policy will only interpret non-print statements, without evaluation. This naturally affects the import of ay structure files as variables since the Structure from file parameter is not evaluated. After the model is interpreted with the workflow executor, these structure variables will have n.c. values.

When the workflow is run (externally), the data for the structure variables is unavailable, thus causing termination of the evaluation with an error message. In particular, if the worflow is run using FireWorks' rlaunch command, the following output is produced:

FileNotFoundError: [Errno 2] No such file or directory: 'GEOMETRY.cif'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
[...]
virtmat.language.utilities.errors.StructureInputError: error occured reading structure

Would this require some sort of special exception for Structure parameters, so that external evaluation of the workflow can be achieved?
