Yes, but probably from Wheezy when before Jessie became the new stable. 
My dpkg -l shows:
ii  python-requests                       2.4.3-6                              all          elegant and simple HTTP library for Python2, built for human beings
ii  python-pip                            1.5.6-5                              all          alternative Python package installer

Yes.

With /usr/local/lib/python2.7/dist-packages/requestsRENAMED
$ python -c "import requests; print requests.__version__"
2.4.3
$ python -c "from requests.compat import IncompleteRead"
$

With the original /usr/local/lib/python2.7/dist-packages/requests:
$ python -c "import requests; print requests.__version__"
2.9.1
$ python -c "from requests.compat import IncompleteRead"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name IncompleteRead

I tried "apt-get purge python-pip python-requests" and then reinstalling 
them to see if the problem would go away. Nope:
$ pip
Traceback (most recent call last):

Again, I renamed the old requests directory for me to use pip again. :(
