[Python-modules-team] Bug#679819: Dropping Provides field broke depending software (python-avogadro)

[Scott Kitterman]

That's a bug in the policy I failed to notice.  It should be restricted to 
packages that build modules only for the non-default version of Python which 
Avogadro doesn't.  One or the other package needs to be changed.  I agree with 
that.

python-avogadro is the only package in the archive that depends on python2.7-
qt4.  I think it makes more sense to fix it there than in python-qt4 and depend 
on a bug in poilcy, but since that's what it says, I'll fix it in python-qt4 if 
you prefer.

Note that XS-Python-Version: current is long deprecated and has never been 
supported by dh_python2, so that part of your package isn't doing anything.

Here's all that's needed:

You'll find that it makes absolutely no difference about what packages are 
pulled in when it's installed.  If you'd be willing to fix it this way, I'll 
take on talking to the release team about it.
