Hello

Nautilus often hangs when used in a particular user account. The hanging ends
with Gnome displaying the Wait/Force Quit dialog box.

I tried using the Nautilus Nightly build Flatpak, and it doesn't hang (flatpak
install --from
https://nightly.gnome.org/repo/appstream/org.gnome.NautilusDevel.flatpakref)

I have 2 accounts on my PC. One seems to be able to use Nautilus without
hanging, the other has frequent hangs.

Regarding the hanging account...

Often when I press the Files icon, the cursor changes to a loading spinner for
less than a second and then turns back into a normal arrow cursor - Files
doesn't open though.

After the above happens, if I press the Meta key to show the Gnome Dash, the
cursor changes back to a loading spinner. Files doesn't open though.

I found an old Ubuntu thread from a few years ago that suggested entering the
following in the terminal

> killall nautilus
> nautilus -q

After doing that, I am able to open Gnome Files by clicking it's icon.
Sometimes I can use it for more than 5 mins, but often it's less. 

On occasion I have left my computer running for several hours, with the hanging
user account logged in, and when I have used Nautilus after these several
hours, I was able to use it for 20 minutes or more. That may be a coincidence
though :-D

I saw in some chat forums that it may be related to tracker, but I didn't
really know what I was looking at regarding journalctl logs (what was normal
etc).
