** 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). + + 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. + + [ Original description ] + The Ubuntu Error Tracker has been receiving reports about a problem regarding gnome-shell. This problem was most recently seen with package version 46.0-0ubuntu5.1, the problem page at https://errors.ubuntu.com/problem/65513baf83b5ba140d09c2aa71b988097108cde0 contains more details, including versions of packages affected, stacktrace or traceback, and individual crash reports.
