[oe] problem with modifications to base.bbclass

[David Hemmo]

Hello,

I am trying to build an image and I run in a python error that seems to be caused by the latest modifications to base.bbclase

ERROR: Error in executing: /home/owner/dvt/oe/oe_shogo2test/recipes/stage-manager/stagemanager-native_0.0.1.bb

it seems the parameters sent to oe_unpack_file are not what the function faits for

def oe_unpack_file(file, data, url = None):

I am too new to this project to propose a patch, but I hope someone will be able to help

Thanks
