### Issue description

Calling TreeItem set_text() on a TreeItem that was removed via remove_child() causes debugging to end and the application to close without any error message.

### Steps to reproduce

Run the included example to get the debugger to crash. Comment out "treeItem.remove_child(subTreeItem)" for normal behaviour.
