We have several reports of the same crash message ("Finalizing proxy for an object that's scheduled to be unrooted: Gio.Subprocess") in Fedora:

Not sure if they all have the same underlying cause. One report mentions the Easy Screen Cast extension, and also claims to have solved the problem by disabling pipewire.service . ** Bug watch added: Red Hat Bugzilla #1466948 https://bugzilla.redhat.com/show_bug.cgi?id=1466948 ** Bug watch added: Red Hat Bugzilla #1517479 https://bugzilla.redhat.com/show_bug.cgi?id=1517479 ** Bug watch added: Red Hat Bugzilla #1514732 https://bugzilla.redhat.com/show_bug.cgi?id=1514732 ** Bug watch added: Red Hat Bugzilla #1522921 https://bugzilla.redhat.com/show_bug.cgi?id=1522921 ** Bug watch added: Red Hat Bugzilla #1523323 https://bugzilla.redhat.com/show_bug.cgi?id=1523323 -- 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/1720768 Title: gnome-shell crashed with SIGTRAP in object_instance_finalize from js::Class::doFinalize ["Finalizing proxy for an object that's scheduled to be unrooted: Gio.Subprocess\n"] Status in gnome-shell package in Ubuntu: Confirmed Bug description: https://errors.ubuntu.com/problem/bcc0785597c2485f446db82f8dfa08eb7dd972a5 --- Logged in with one new user, switched to login under another account.
