I’m encountering a similar crash, this time in "g_type_check_instance_is_fundamentally_a", and not "g_type_check_instance_cast". Attached are the gdb.txt and journalctl.txt files generated following the procedure given above.
This time it seems that it is coming from another extension, Pomodoro, that I’ve been using without any crash before upgrading to Ubuntu 17.10. So it looks like this regression could potentially affect other extensions. ** Attachment added: "gdb.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1714989/+attachment/4985108/+files/gdb.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1714989 Title: gnome-shell crashed with SIGSEGV in g_type_check_instance_cast() from st_label_set_text() (dash-to-panel specific?)
