This behavior only started after this morning's pile of updates.
I run GNOME with Wayland, and whenever I try to move a file in Nautilus, the GNOME session crashes, and I'm thrown into a console.
I tried an older kernel, and the behavior is the same.
This only happens in Wayland. In an X11 session, everything works, so the workaround is to run X11.
I saw that gnome-shell was one of the packages upgraded today. Is that where a bug should be filed?
I don't know where to look for this in the logs.
