[Bug 1997912] Proposed package removed from archive

[Steve Langasek]

The version of apport in the proposed pocket of Kinetic that was
purported to fix this bug report has been removed because one or more
bugs that were to be fixed by the upload have failed verification and
been in this state for more than 10 days.

** Changed in: apport (Ubuntu Kinetic)
       Status: Fix Committed => Confirmed

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.
