To Reproduce

1. Open an app that has two pages one of which containing a list view.
2. Navigate back and forth between the two pages.
3. Observe when the app crashes once navigated to list view (occasionally).
4. Read the error in the terminal.

Expected behavior
The application does not crash. At least, it displays a warning.

Sample project

Unfortunately none yet, but I will create a sample project that has this bug if needed.
