Ubuntu 20.04: Running /usr/bin/nautilus from the terminal invokes nautilus-dropbox instead

[superclarkk]

See the discussion in the dropbox community. I'll repeat the OP here.

Environment

Ubuntu 20.04
Dropbox 2020.03.04
GNOME nautilus 3.36.3

Problem Description

Since an OS update this morning, when I run nautilus from the terminal, it invokes, nautilus-dropbox, returning the message, "Initializing nautilus-dropbox 2020.03.04", and blocks the terminal (as there's a process running, I can't type anything until I press CTRL+C). Before the update, running nautilus functioned properly, and did not block the terminal.

I've tried purging dropbox (apt purge dropbox) and reinstalling. I've also rebooted the system.

The file manager can be opened from Gnome, seemingly as normal, although that doesn't mean that the problem isn't also happening in the background.

Issue #114 seems similar, but I'm not sure it's the same. If you need any more info, let me know.

nautilus-dropbox files on my system:

/usr/lib/nautilus/extensions-3.0/libnautilus-dropbox.so

ls -l /usr/bin/nautilus

Noticed in #96, but this is a much better issue report.
