Can we get a fix for this pushed to unstable/testing and then backported
to wheezy ?

We have some infrastructure relying on this module to parse dependencies
(my use case: backend scripts of tracker.debian.org) and we currently
get tons of warnings like this:
deb822.py: WARNING: cannot parse package relationship "python:any (>= 2.6.6-7~)", returning it raw

It's really annoying.

Note that dpkg is accepting any valid architecture string and I suggest
that you fix the code to accept the same (see parse_string() in
/usr/share/perl5/Dpkg/Deps.pm), basically the regex for the architecture
is a simple: [a-zA-Z0-9][a-zA-Z0-9-]*

You could also add support for "restrictions" which will be used in the
future to implement bootstrapping build profiles (that is content in <>
put after the dependency).

Thanks!
