On Tumbleweed (currently version 20221031, but problem started earlier)
starting GNOME's file-browser nautilus automatically launches the
nextcloud-desktop client with NO way to prevent this behaviour. The client is
launched every time the file browser or indeed even if the file-picker is
started from firefox or wherever. And this happens no matter if the user has an
account or not (the client may be installed because other users on the same
system may have accounts, but I doubt anyone would want this behaviour to
happen to them by default, sync accounts or not). There is no way to turn this
behaviour off, no checkbox, option, or anything from inside the client.

After a bit of head-scratching about this highly annoying issue, I figured out
that this happens due to an apparently very botched libcloudproviders
integration from nextcloud-client, as documented in the following upstream bug
reports (un-resolved as of this date):

* https://github.com/nextcloud/desktop/issues/1982
* https://github.com/nextcloud/desktop/issues/2622

Please fix this behaviour so that I do not have to go around installing or
removing a bunch of machines I administer or, worse, have to do something
manually after every nextcloud-client update. So far, I have been getting
around (on my personal system) by commenting put the
"/usr/share/cloud-providers/com.nextcloudgmbh.Nextcloud.ini" file, but that
gets over-written on every update.

I submitted what I felt was a possible fix [1], but it seems to be not
acceptable to the maintainer. So this is a request to have the nextcloud-client
behaviour of starting up on file-browser launch some other way. Thanks in
advance.
