[Python-modules-team] Bug#865359: Strange breakage

first, sorry I didn't answer faster.

Your report starts by telling that ipython breaks when trying something,
but you don't tell me how it breaks.

Then you show me the commands you used to uninstall a few packages using
dpkg, then pip.

Finally, you show an apt-get command to install package, but then that
is followed by a python error...

Here is what happens here (I'm on unstable though) :
jpuydt at nox:~$ python

In [1]: from backports.shutil_get_terminal_size import get_terminal_size

so the package seems to work as intended. Since the package is in use in
ipython+sagemath since long, I am surprised to have only a single
report. There must be something special to your system to explain the issue.

The only trace you mention in your mail seems to imply the breakage is
because the package is *not* installed -- while it should, since it's a
depends. Let me try a wild guess : the problem isn't in my package, but
in another one, which fails to declare the dependency and hence gets
broken -- in which case we can close that bug report and open another
one against the real culprit.

Can you check and tell me if I hit the nail?
