  To: 70073

## System Information:

* Kernel: 6.8.2-2
* DE: Gnome 46.0
* WM: Mutter (Wayland)
* gnome-shell: 46.0
* wayland: 1.22.0
* mutter: 46.0
* wl-clipboard: 2.2.1
* weston: 13.0.0
* sway: 1.9-e93da93
* emacs package: emacs-wayland 29.3-1.1 (archlinux)

## Steps to reproduce the issue under Gnome:

1. Invoke `emacs -Q` in any terminal emulator to start Emacs along with
   its GUI frame.
2. Mark/highlight some area of text with your mouse pointer. OR use
   C-Space and keyboard movement shortcuts to do the same.
3. Open any other application. (gnome-text-editor, for example)
4. Use your middle mouse button in an editable text area of the second
   application's frame.
5. Emacs crashes.

NOTE1: Emacs doesn't crash if you just middle click in any 
       *non-textual/non-editable* area, outside Emacs.
NOTE2: Middle clicking *inside* any of Emacs' own buffers DOES work
       properly without any crash or noticeable problem.
NOTE3: The problem is reproducible both when marking with mouse cursor
       or when marking with keyboard shortcuts.
NOTE4: Using another shortcut that pastes the Primary selection of the
       wayland, instead of mouse's middle click, also reproduces the 
       same issue. E.g. S-Insert of WezTerm.
NOTE5: Marking a text outside of Emacs and middle clicking inside
       Emacs works flawlessly.

## State of the issue under Sway:

The issue is completely reproducable under sway with the same steps as
above, with the same symptoms and the same segmentation fault error.

## State of the issue under Weston:

The issue is not reproducable under Weston but the functionality is
also lost.  Weston doesn't support primary selection.

## Tried Workarounds:

### Workaround number 1:
Disable the primary selection.  In gnome you can disable 
primary selection.  Brings users to the same state of under 
Weston.  Emacs will not crash, Primary selection works inside 
Emacs, but not outside of Emacs.

Emacs still crashes if user uses the middle click inside applications
that try to pull primary selection with middle click.

### Workaround number 2:
Set variable `select-active-regions` to `nil`.	Disables the
functionality and of course removes the issue.

## Terminal log of Emacs after crash:
