Create a new Footprint Wizard Selection Generator is broken on recent KiCad nightly releases

[Joe Silva]

Recent April KiCad nightly releases have broken the Create a New footprint feature. When you select one of the Available Footprint Generators windows outputs an error window. " Exception on python footprint wizard code" " Track back (most recent call last):"

I have attached a copy of the window screen showing the error. This issue was not present in the early March KiCad nightly release codes.
