I have (what looks like) the same issue with another extension (specifically this commit: https://github.com/projecthamster/hamster- shell-extension/tree/07cea1824291cb818befd5fb473a065abe334bde).
The crash does not always happen (is it a race condition?), but, when it does, it always occurs right when clicking on a button to close a window. JS and GDB stack traces are below, and I can provide a core dump and other debugging info if necessary. -------------- JS stack trace : org.gnome.Shell.desktop[2778]: == Stack trace for context 0x562dad808000 == org.gnome.Shell.desktop[2778]: #0 0x7ffdd07c5520 b /home/fx/.local/share/gnome-shell/extensions/[email protected]/widgets/panelWidget.js:245 (0x7fa98fe16890 @ 105) org.gnome.Shell.desktop[2778]: #1 0x7ffdd07c5580 I resource:///org/gnome/gjs/modules/_legacy.js:82 (0x7fa9e83c2c48 @ 71) org.gnome.Shell.desktop[2778]: #2 0x7ffdd07c5650 b /home/fx/.local/share/gnome-shell/extensions/[email protected]/widgets/panelWidget.js:186 (0x7fa98fe16670 @ 208) org.gnome.Shell.desktop[2778]: #3 0x7ffdd07c56f0 I self-hosted:917 (0x7fa9e83ee4d8 @ 394) org.gnome.Shell.desktop[2778]: #4 0x7ffdd07c57c0 b resource:///org/gnome/gjs/modules/overrides/Gio.js:90 (0x7fa9e8103670 @ 118) kernel: gnome-shell[2778]: segfault at 100000016 ip 00007faa120f3e0d sp 00007ffdd07c4e30 error 4 in libgobject-2.0.so.0.5400.1[7faa120be000+52000] GDB stack trace : #0 0x00007f4c409ece0d in g_type_check_instance_cast () at /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #1 0x00007f4c3e15a768 in st_label_set_text (label=0x555574a9df60, text=0x55557754b990 "No activity") at ../src/st/st-label.c:331 #2 0x00007f4c3a64be18 in ffi_call_unix64 () at /usr/lib/x86_64-linux-gnu/libffi.so.6 #3 0x00007f4c3a64b87a in ffi_call () at /usr/lib/x86_64-linux-gnu/libffi.so.6 #4 0x00007f4c3f6af3c8 in () at /usr/lib/libgjs.so.0 #5 0x00007f4c3f6b0ca4 in () at /usr/lib/libgjs.so.0 #6 0x00007f4c3763fe6c in () at /usr/lib/x86_64-linux-gnu/libmozjs-52.so.0 #7 0x00007f4c37632eca in () at /usr/lib/x86_64-linux-gnu/libmozjs-52.so.0 #8 0x00007f4c3763f6d6 in () at /usr/lib/x86_64-linux-gnu/libmozjs-52.so.0 #9 0x00007f4c3763fcaf in () at /usr/lib/x86_64-linux-gnu/libmozjs-52.so.0 #10 0x00007f4c3763ff89 in () at /usr/lib/x86_64-linux-gnu/libmozjs-52.so.0 #11 0x00007f4c37433d09 in () at /usr/lib/x86_64-linux-gnu/libmozjs-52.so.0 -- 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 ??
