Bug description:
  [ Description ]

  I'm creating this bug report to have a place to describe the proposed
  backport of glib2.0 2.62.4-1 from focal.

  One purpose of this backport is to fix bug #1844853.

  But there are several other changes. Here's the diff of NEWS:

  +Overview of changes in GLib 2.62.4
  +==================================

  +
  +* Bugs fixed:
  + - #1938 GDateTime doesn't support leap seconds

  +
  +Overview of changes in GLib 2.62.3

  +  FD limits (#954)
  +
  +* Fix undefined behaviour with `g_utf8_find_prev_char()` (#1917)
  +
  +* Bugs fixed:

  + - #1916 objcopy not used from cross-compilation file in GIO tests
  + - #1917 Test utf8-pointer fails with static build, LTO, optimisations, and new GCC
  + - !1174 Backport !1164 “use-after-free fix in mimeapps test” to glib-2-62

  + - !1228 Backport !1199 “gunicode: Fix UB in gutf8.c and utf8-pointer test” to glib-2-62
  +
  +
  +Overview of changes in GLib 2.62.2
  +==================================
  +
  +* Bugs fixed:
  + - #1896 Use after free when calling g_dbus_connection_flush_sync() in a dedicated thread

  + - !1156 Backport !1146 Solaris fixes to glib-2-62

  This release can be considered to be tested under
  https://wiki.ubuntu.com/StableReleaseUpdates/GNOME

  There are patches from the upstream master branch rather than this
  stable release:

  + Add-a-test-for-GDBusServer-authentication.patch
  + gdbus-server-auth-test-Create-temporary-directory-for-Uni.patch
  + gdbus-server-auth-test-Include-gcredentialsprivate.h.patch
  + Make-ld-executable-configurable.patch

  They are sensible backports which I hope are appropriate for SRU.

  [ QA ]

  The testsuite fixes will verify themselves during the build and
  autopkgtest.

  For the rest of the fixes, please exercise the desktop thoroughly. Log
  in, log out, run many applications and make sure there are no
  regressions.

  [ Regression potential ]

  test fixes> Build failures or autopkgtest failures.

  GLib is a central desktop library. Regressions could break any part of
  the desktop - so QA is important, the SRU exception notwithstanding.
