5.2.1.1 crashes when width set to auto

[Matthew Low]

When setting a width (the higgs, for example) to auto in param_card.dat, running generate_events crashes with the error:

Command "generate_events -f" interrupted in sub-command:
"set complex_mass_scheme False" with error:
NameError : name 'MW' is not defined

Please attach this file to your report.

Doing the same thing in 5.2.0.2, everything worked fine. Here's the MG5_debug also. Thanks!
