Well, the solution was pretty simple.
in line 171 of SubmitHoudiniToDeadline.py, SaveStickyProp function was hanging up on at least job priority number.
So just added str() string conversion around the dialog value, and that fixed it.
def SaveStickyProp( config, stickyProp ):
global dialog
config.set( "Sticky", stickyProp, str(dialog.value( stickyProp + ".val" )) )
