Bug description:
  [Impact]

  The autopkgtests are sometimes passing, sometimes stuck for more than 2h:
  http://autopkgtest.ubuntu.com/packages/apport/cosmic/amd64.
  It's blocking randomly on different tests.

  All tests that are stucked, implements closing a request via a timeout
  (and then, executing "run"). The bet is that the timeout is short
  enough (1s) so that, when autopkgtests infra is busy, time to execute
  the bash subcommand is taking more than a second, and so "dismissing"
  is ran before execution happens and the whole testsuite hangs.

  There are few instances of setting this timeout function:
  $ grep eout_add_sec test/*
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, cont)
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, cont)
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, cont)
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, c)
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, c)

  Short term solution could be to increase the timeout. Long term would
  be to eliminate this potential race implementing cancelling
  differently. The short term workaround to increase the timeout
  increases the test execution time by five minutes.

  [Test Plan]

  Check that the autopkgtest succeed on all architectures (except for
  i386).

  [Where problems could occur]

  The test cases are only part of the apport source package and are not
  copied in any binary packages. Changes to the test will only affect
  the package build and test execution.
