update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
kinetic to verification-done-kinetic. If it does not fix the bug for
you, please add a comment stating that, and change the tag to

Bug description:
  Impact
  ======

  apport-unpack and whoopsie-upload-all can crash when fed with a
  malformed problem report. They should print a proper error message
  instead of crashing.

  Test Plan
  =========

  1. Create malformed report:
  ```
  printf "CoreDump: base64\n H4sICAAAAAAC/0NvcmVEdW1wAA==\n 7Z0LYFPV/cdP0rQ\n" > malformed.crash
  ```
  2. Try to unpack it:
  ```
  apport-unpack malformed.crash unpack
  ```

  It should print an error message instead of a stack trace.

  Where problems could occur
  ==========================

  The patch touches the problem report handling and therefore can affect
  apport-unpack, apport-bug, whoopsie-upload-all. The change is covered
  with tests and apport has a test suite running during build and as
  autopkgtest.
