Quack,
I stumbled into such false positive while preparing a new upstream
release.
$ dpkg -I weboob_1.3-1_all.deb | grep Depends
Depends: python:any (<< 2.8), python:any (>= 2.7.5-5~), python-weboob
(>= 1.3-1), python-html2text, python-prettytable
$ lintian weboob_1.3-1_all.deb
E: weboob: python-script-but-no-python-dep usr/share/weboob/imm-o-matic
E: weboob: python-script-but-no-python-dep
usr/share/weboob/replace-backends-pass.py
So maybe the test do not cope with versioning or maultiarch. This was
generated with ${python:Depends}.
Regards.
