Bug description:
  [Impact]
  packagekit (sometimes) crashes when there are errors.

  https://errors.ubuntu.com/problem/1bdc3e539949aa164d276979f62ca0282a54fcbd
  https://errors.ubuntu.com/problem/e9af46c2ad01a15f968379c434fe0bfbf924d034

  [Test case]
  Check that there are no further cases on the error tracker with the proposed version.

  [Regression potential]
  Given that this just changes the return type of a function only used in calls, and the code compiles, there should be no possibility for a regression. Of course, if there were, it'd be segfaults or stuff.
