Crash in clutter_actor_child_model__items_changed after opening export dialog in GIMP

### What Happened?

I got a session crash after trying to export a JPEG in GIMP.

### Steps to Reproduce

(I was not able to reproduce the issue myself, but this is what I was doing when I got the crash)

GIMP installed from AppCenter, non-system-wide.

1. Open JPEG file in GIMP through the *Open with...* context menu in Files
2. Crop something
3. Export using Ctrl+Shift+E (should open an export dialog)
4. See session crash

### Expected Behavior

No crash.

### OS Version

8.x (Circe)

### OS Architecture

amd64 (on most hardwares)

### Session Type

Secure Session (Wayland, This is the default)

### Software Version

Early Access or Compiled from git
