I noticed this completely misfiled RFP bug, which seems to be an actual
upgrade problem for dh-python/1.20140511-1~bpo70+1 (file conflicts with
python).

This only seems to be a problem if upgrading from 1.20131021-1 [1], if upgrading from 1.20131021-1~bpo70+1 [2] doesn't seem to do this.

However, I can't properly install 1.20131021-1 on wheezy, hence I don't think this is something we need to worry about. Either the person had broken install, or a custom package with fixed dependencies. My understanding is that wheezy doesn't support the "python3:any" syntax for dependencies.
