I pulled down the fix and am able to start the tuskar-api, though attempts to access it result in database errors (note, dbsync works fine for me)... I don't know if this is related or not, just in case here is the stack trace from trying to run "python tools/initial_data.py"

ERROR:wsme.api:Server-side error: "(OperationalError) unable to open database file None None". Detail:
