Comment 8 for bug 1813171

Most likely to be this: https://gitlab.gnome.org/GNOME/nautilus/-/issues/3036

There's a fix, but it's hard to verify as this bug is very fickle in the scenario described by this report. There's only one known case where it's consistently reproducible, which is to open 2 files with nautilus in the "Open With..." dialog.
