Bug Description

Package: python3-defaults
Version: 3.2.3-5

I was building a deb package using python3 in my PPA. I want to specify a range of python3 version, but dh_python3 causes an error as follows if the maximum version is specified:

Traceback (most recent call last):
  File "/usr/bin/dh_python3", line 490, in <module>
    main()
  File "/usr/bin/dh_python3", line 422, in main
    dependencies.parse(stats, options)
  File "/usr/share/python3/debpython/depends.py", line 158, in parse
    self.depend("python3 (<< %s)" % vrepr(vr[1] + 1))
TypeError: can only concatenate tuple (not "int") to tuple

I specified the python3 version in debian/control as follows:

  X-Python3-Version: >= 3.2, << 3.3

The same error happens when I use -V command line option like:

  dh_python3 -V 3.2-3.3

I'm using dh_python3 only for private modules, not for public modules.

I didn't replicate this. Can you provide a package that demonstrates the
problem?

I encountered the problem in my Blender's PPA:

  ppa:irie/blender

You can see build log of the FTBFS:

  https://launchpad.net/~irie/+archive/blender/+build/3876314

Since Blender requires many libraries which are not officially debianized yet, you have to use some other PPAs if you want to test my blender package:

  ppa:irie/opencollada-builddep
  ppa:irie/ocio-static
  ppa:irie/openimageio (optional, maybe Ubuntu's offical package can be used instead)

Anyway, as I mentioned in Debian's tracker, each element of vr[] in depends.py is a tuple of the major and minor versions such as (3, 2), not an integer, so "vr[1] + 1" in the line 158 absolutely causes a TypeError.

Similar error in dh_python2 has been reported:

However, this issue seems not to be fixed yet.

As predicted, I had trouble building the version of blender in your PPA, so I
copied your packaging changes (less build-deps) into the Quantal package and
tried that. It built fine:

make[1]: Entering directory `/home/blender-2.63a'
dh_python3 -V 3.2-3.3 /usr/share/blender/2.63/scripts \
                   -X usr/share/blender/2.63/scripts/addons_extern
make[1]: Leaving directory `/home/blender-2.63a'

So while I don't doubt there's a bug here, I'm not sure exactly when it gets
triggered. I'm glad to work on this, but until I can recreate the problem,
I'm not going to be comfortable I've got a correct solution.

I can redo FTBFS by very simple deb package (py3test) I attached.

Please check it.
