Bug#711988: lintian: Lintian does not recognize python:any dependency

[Francois Gouget <fgouget@free.fr>]

Package: lintian
Version: 2.5.13
Severity: normal

Dear Maintainer,

I have a 32-bit multiarch package that also includes Python scripts. The scripts don't need a 32-bit Python interpreter so the depend is 'python:any' as described on the Multi-Arch specification(*):

https://wiki.ubuntu.com/MultiarchSpec#Extended_semantics_of_per-architecture_package_relationships

But when I do that Lintian gives me this error:

E: testany: python-script-but-no-python-dep usr/bin/pyhello

If I remove the ':any' the error goes away. This leads me to conclude the Lintian gets confused when dependencies have architecture specifiers.

I uploaded a test package there:
http://fgouget.free.fr/bugs/testany_1.0-1.tar.gz
http://fgouget.free.fr/bugs/testany_1.0-1_i386.deb


(*) In my tests the ':any' is indeed necessary to not force the user to install 32-bit Python binary, even though the python package itself is architecture 'all'. This must be because the packages it depends on are not architecture 'all'.
