this is still happening!

i suspect the reason is because
python-backports-shutil-get-terminal-size ships a __init__.py file
upstream and that's the one that's actually being installed, while all
the other packages overriding dh_python2 to add "--namespace
backports" would install a file with a different content.

cfr:

$ cat /usr/lib/python2.7/dist-packages/backports/__init__.py
__path__ = __import__('pkgutil').extend_path(__path__, __name__)

as installed by python-backports.ssl-match-hostname

with

$ cat backports/__init__.py
from pkgutil import extend_path
__path__ = extend_path(__path__, __name__)

as installed by python-backports-shutil-get-terminal-size; and if you
try to install them both:

Selecting previously unselected package
python-backports-shutil-get-terminal-size.
(Reading database ... 586099 files and directories currently installed.)
Preparing to unpack
.../python-backports-shutil-get-terminal-size_1.0.0-4_all.deb ...
Unpacking python-backports-shutil-get-terminal-size (1.0.0-4) ...
dpkg: error processing archive
/var/cache/apt/archives/python-backports-shutil-get-terminal-size_1.0.0-4_all.deb
(--unpack):
trying to overwrite
'/usr/lib/python2.7/dist-packages/backports/__init__.py', which is
also in package python-backports.functools-lru-cache 1.4-1
Errors were encountered while processing:
/var/cache/apt/archives/python-backports-shutil-get-terminal-size_1.0.0-4_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

this means either any of the other backports packages are installed or
ipython is not installable (as it depends on
python-backports-shutil-get-terminal-size)

can you please fix this asap?

Thanks,
