I see this in v.lidar.mcc:

grass.run_command('v.outlier',
	input=nc_points, output=temp_ncout, outlier=temp_ng,
         ew_step=xs_s, ns_step=ys_s, lambda_=f, threshold=t,
         filter='positive',
         overwrite=True, quiet=True, stderr=nuldev)


I guess the stderr=nuldev is the reason why no error message appears.

Maybe this call should be in a try-except check ?
