Hello,
I can confirm that the package python-backports-shutil-get-terminal-size
breaks ipython in stretch with a traceback as described in initial bug
report. It also breaks the sagemath package (the CLI sage command) for
the same reason.
I quick-fixed it thusly (diff -u):

-------[ end patch ]-----------------
Then both ipython and sage can start without a traceback.
Some package versions:
ii ipython 5.1.0-3
ii python-backports-abc 0.5-1
ii python-backports-shutil-get-terminal-size 1.0.0-3
ii python-backports.ssl-match-hostname 3.5.0.1-1
ii python-ipython 5.1.0-3
ii python3-ipython 5.1.0-3
ii sagemath:amd64 7.4-9
ii sagemath-common 7.4-9
Best regards
