Details:

This should instead produce a RelaxError explaining the problem.  It was
uncovered by the system test which performs a very minimal model-free
analysis using the OMP relaxation data.  The traceback is:


relax> fix(element='all', fixed=False)

relax> model_selection(method='AIC', modsel_pipe='final', pipes=['local_tm',
'sphere'])
AIC model selection.

Model index 0.
