Description:

When I try to launch nautilus, nemo or thunar the application segfaults immediately.

$ nemo

(nemo:30343): GLib-GObject-CRITICAL **: g_type_interface_peek: assertion 'instance_class != NULL' failed
Segmentation fault (core dumped)

The following is logged in journalctl:

All three applications produce the same stderr message and a stack trace ending in g_file_get_parse_name.

If someone can confirm that downgrading glib2 is safe to do so then I'll downgrade through the versions and figure out where this was introduced, if that helps.

Additional info:

glib2 2.52.3-1
nemo 3.4.6-1

Steps to reproduce:

$ nemo
