Hey there,
I am experiencing a segmentation fault in gnome-shell on bootup since upgrading to gnome 3.26. . This happenend first sometimes in october 2017. I tried several times since then with the newest version (3.26.1 and 3.26.2), in hope the bug might be fixed, but I had no luck. Last time was today.
Are there anymore ways to debug the segfault in a better way? The relevant output of journal -xe is:
