I have the same problem on ubuntu 17.10 with gnome shell 3.26.0 Bug usually occurs while tabbing between active windows. The effect is the screen freezing for some time and when it comes back gnome-shell restarting (looks same as restarting it with "ALT+F2, r").
I do not have actual reproduction steps as it does not seem to occur consistently on my machine, just about once per week. I have ibus-mozc installed and after each crash it stops reacting to hot keys. Manually changing input method from the toolbar brings it back to life making hotkeys work again. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/869571 Title: gnome-shell crashed with SIGSEGV in g_type_check_instance_cast() Status in gnome-shell package in Ubuntu: Invalid Bug description: Crashed while watching a video ProblemType: Crash DistroRelease: Ubuntu 11.10 Package: gnome-shell 3.2.0-0ubuntu1 ProcVersionSignature: Ubuntu 3.0.0-12.19-generic 3.0.4 Uname: Linux 3.0.0-12-generic x86_64 NonfreeKernelModules: fglrx ApportVersion: 1.23-0ubuntu2 Architecture: amd64 CrashCounter: 1 Date: Fri Oct 7 01:14:13 2011 ExecutablePath: /usr/bin/gnome-shell InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Alpha amd64 (20110803.1) ProcCmdline: /usr/bin/gnome-shell ProcEnviron: LANGUAGE=en_GB:en PATH=(custom, no user) LANG=en_GB.UTF-8 SHELL=/bin/bash SegvAnalysis: Segfault happened at: 0x7f0ee77f856c <g_type_check_instance_cast+60>: movzbl 0x16(%r8),%eax PC (0x7f0ee77f856c) ok source "0x16(%r8)" (0x1af5de016) not located in a known VMA region (needed readable region)! destination "%eax" ok SegvReason: reading unknown VMA Signal: 11 SourcePackage: gnome-shell StacktraceTop: g_type_check_instance_cast () from /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 ??
