Title:
  armhf autopkgtests fail due to
  TestApportValgrind.test_valgrind_min_installed

Status in apport package in Ubuntu:
  New

Bug description:
  autopkgtests are pretty reliably failing[1] on armhf due to the
  following (single) test failure:

  638s E       Diff is 1134 characters long. Set self.maxDiff to None to see it.

  638s tests/integration/test_apport_valgrind.py:43: AssertionError

  This could be related to valgrind functionality being different on
  armhf, it could also be related to integer sizes internally on armhf.
  I haven't looked too deeply into it.
