Nautilus goes berserk when trying to switch to list view in Trash

[teo1978]

Steps to reproduce:

1. open Nautilus
2. Select icons view
3. open Trash
4. try to switch to list view by clicking on the button on the top right

Expected: should immediately switch to list mode. There's no acceptable valid reason for this to be slow. But if, for whatever valid reason, it did require a perceivable amount of time (which btw is an assumtion you should always make when designing the UI, because even a few milliseconds can be perceivable enough that visual feedback needs to be given and interaction can happen meanwhile), you should see a spinning icon somewhere giving you visual feedback that something is being processed (and you should be able to instantly go back to icons mode)

Observed: it remains in icons mode as if you hadn't clicked anything (despite the fact that the list mode button becomes apparently selected). I have no idea whether it simply ignores you and doesn't switch to list mode without any error message, or if it's actually processing and taking long because Nautilus sucks and is slow and inefficient, but gives no visual feedback that it's processing something.

But it doesn't end here:

4. Close Nautilus and open it again
5. Switch to list mode BEFORE you open trash (succesfully switches)
6. Open Trash

=> Now the Trash appears empty, even though it's not. Again, no idea whether it's loading and taking long: there's no indication of it.

7. Try to switch back to icon mode:

=> goes back to the folder you were browsing before, and does switch to icons mode.

It's all a fucking mess

- something is way slower than it should
- the UI seems to be designed around the (never correct and in this case false) assumption that everything happens instantly, so there's no feedback when you need to wait because something is being loaded, and when that happens and you keep doing stuff, the behavior becomes inconsistent and everything goes completely berserk.

This is fucking pathetic.

And don't start with "You are using an old version of Ubuntu bla bla bla".
I am using an old version because of an unrelated disgraceful regression in Nautilus itself which renders it completely unusable from Ubuntu 17.04 onward ana that to this day hasn't been fixed, of which luckily enough I became aware before I upgraded, so I stuck with 16.04.
Furthermore, 16.04 is LTS and hasn't reached EOL yet, so bugs that render the system completely unusable like this one have to be fixed and the fix has to be released to 16.04.

Anyway I don't give a fuck. I'm sick of Ubuntu and I'm switching to OpenSuse soon.

Oh, here's another quirk:

When I click the Trash icon in Nautilus, Nautilus's Launcher icon immediately disappears, even though its window doesn't.

It happened me a few times and each time I thought I had closed the window and forgotten, but then I realised, by minimizing all other windows one by one, that several Nautilus windows were still there.

Pathetic. And this isn't just a bug in Nautilus (I'm sure the main triggering reason is a bug in nautilus), it's also a bug in whoever is responsible for managing windows (Xorg? Compiz? I have no idea), because it should never allow to hide a launcher icon for a window that remains open. That's an inconsistent situation that should just be forbidden at the deepest level.

The whole thing is such a fucking mess.
