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. This is the most occurring apport bug in Ubuntu
  22.10 (kinetic) with as of writing 14,822 reported crashes.

  Test Plan
  =========

  1. Create malformed report:
  ```
  echo > 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.
