I also experience this crash. I don't have global app menu installed but for me the crash occurs when the following line of code is being executed in the Freon shell extension: https://github.com/UshakovVasilii /gnome-shell-extension- freon/blob/f9756b2430b3766c3d21d71e9928963032617bf7/freon%40UshakovVasilii_Github.yahoo.com/extension.js#L360
I've attached a valgrind log of the crash occurring. There is a whole lot of seemingly related bad memory access before the crash occurs. For me it happens sometimes immediately after logging in, but before the shell successfully loads. I assume it only happens if the Freon extension is installed. I'm on version 29 of the freon shell extension. ** Attachment added: "Valgrind log of crash occurring" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1714989/+attachment/4999830/+files/17-10-30_15-38-21.valgrind -- 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/1714989 Title: gnome-shell crashed with SIGSEGV in g_type_check_instance_cast() from st_label_set_text() from ffi_call_unix64() [Global App Menu specific?] Status in GNOME Shell: Confirmed Status in gnome-shell package in Ubuntu: Incomplete Bug description: Saw some reports with the same title but they're all for previous versions. error report: https://errors.ubuntu.com/problem/1c95cc2653ab00054b5d1764e41d974328a5f49d ProblemType: Crash DistroRelease: Ubuntu 17.10 Package: gnome-shell 3.25.91-0ubuntu2 ProcVersionSignature: Ubuntu 4.12.0-12.13-generic 4.12.8 Uname: Linux 4.12.0-12-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia ApportVersion: 2.20.7-0ubuntu1 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Sep 4 16:52:13 2017 DisplayManager: gdm3 EcryptfsInUse: Yes ExecutablePath: /usr/bin/gnome-shell InstallationDate: Installed on 2017-04-21 (135 days ago) InstallationMedia: Ubuntu 17.04 "Zesty Zapus" - Release amd64 (20170412) ProcCmdline: /usr/bin/gnome-shell ProcEnviron: LANGUAGE=en_GB:en PATH=(custom, user) XDG_RUNTIME_DIR=<set> LANG=en_GB.UTF-8 SHELL=/bin/bash SegvAnalysis: Segfault happened at: 0x7fd97c8e7e5d <g_type_check_instance_cast+77>: movzbl 0x16(%rax),%edx PC (0x7fd97c8e7e5d) ok source "0x16(%rax)" (0x0000eb1e) not located in a known VMA region (needed readable region)! destination "%edx" ok SegvReason: reading NULL VMA Signal: 11 SourcePackage: gnome-shell StacktraceTop: g_type_check_instance_cast () from /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 st_label_set_text () from /usr/lib/gnome-shell/libst-1.0.so ffi_call_unix64 () from /usr/lib/x86_64-linux-gnu/libffi.so.6 ffi_call () from /usr/lib/x86_64-linux-gnu/libffi.so.6 ??
