Crash on opening a window in Gnome 3.24.1

[evaryont]

I'm not sure how to debug this, but gnome-shell seems to crash when I open a new window in a fresh session.

When I enable shellshape during a session, it seems to work as expected. But if I log out and then log in, the first window I open immediately closes the session, putting back at the login screen (gdm).

Looking through journalctl --user, I can only guess that these log lines are related:

Running in Archlinux.

I noticed I had some updates pending, and updated to 3.24.2. It still crashes.

Here is the full log, including installation. I open Epiphany, install the extension (after deleting it with gnome-tweak-tool), close epiphany, and then attempt to open a terminal. So I don't even have to log out first to cause the crash.

There's definitely a bug in gnome-shell or one of its native components here, since JS extensions like shellshape can't themselves cause a segfault (signal 11). Nothing in this log points to an obvious shellshape bug to me, so I don't know that there's much I can do. It looks like you may be running wayland; you could try running with X instead?

[evaryont]

gnome-shell v3.24.3 on X11 does indeed work. I had another segfault when I first enabled the extension. However, after logging back in from GDM it seems to be working well. I'll try it again within Wayland, see if some update between then and now as improved the situation.
