** Description changed: [ 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). + 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/65513baf83b5ba140d09c2aa71b988097108cde0 [ 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.
