Bug description:
  [ Impact ]

  gnome-shell crashes with SIGSEGV in st_theme_node_lookup_shadow() when
  the screen is locked from the overview, if you had any extension
  loaded that changes stylesheets (like ubuntu-dock or dash-to-dock). In
  theory it could happen whenever such an extension is deactivated.

  https://errors.ubuntu.com/problem/9e0eb2f488ad83e41a8977709955a661857ba95e

  [ Test Plan ]

  1. Log into gnome-shell.
  2. Ensure Ubuntu Dock is active.
  3. Open the overview by tapping the Super key.
  4. Lock the screen while the overview is open.

  Expect: No crash, no automatic return to the login screen. The screen
  should lock and then be unlockable.

  Note: It doesn't crash reliably every time due to the nature of memory
  corruption so additional verification under Valgrind may be advisable.

  [ Where problems could occur ]

  Since the fix affects theming and stylesheets, bugs could occur in
  shell theming.
