Hmm, as far as I can tell, Qreator 16.06.1-1 and python-qrencode 1.2-1
are no longer affected by this bug. This means that it should be fixed
in Ubuntu Zesty (17.04) upwards. I guess that leaves.. Xenial?

Bug description:
  [Impact]
  python-qrencode is currently broken for all users in yakkety due to the removal of Image.fromstring from pillow.

  The fix is to replace all calls to Image.fromstring with
  Image.frombytes.

  [Test Case]
  Run the following script and see if it ends in an exception:

  ```
  import qrencode
  qrencode.encode_scaled("foo", 1)
  ``` 

  [Regression Potential]
  It's unlikely that python-qrencode can regress any further, because in its current state, both exported python methods are completely broken and will throw an exception unconditionally with the pillow version in Yakkety.

  [Other Info]
  rdeps may also be broken if they use Image.tostring on the output. So far, the only known rdep that is broken is qreator.

  Below is the stack trace and exception thrown by the broken version of
  qrencode.
