AttributeError: 'NoneType' object has no attribute 'get_id'

When the selection automatically change to another element when I just delete a task (after confirming) :

Context: Global generic exception

Traceback (most recent call last):
  File "/usr/lib/python3.13/site-packages/GTG/core/plugins/api.py", line 68, in __selection_changed

Software versions:

• Getting Things GNOME! 0.6.0
• CPython 3.13.7 (main, Aug 15 2025, 12:34:02) [GCC 15.2.1 20250813]
• GTK 3.24.50, GLib 2.84.4
• PyGLib 3.52.3, PyGObject 3.52.3
• Linux-6.12.44-3-MANJARO-x86_64-with-glibc2.42

So for now I naively rewrote the function as this for temporary fix by adding a None check :

    def decide_button_mode(self, button, task):
        if task is None:
            return
        
        if self.is_task_active(task.get_id()):
            self.change_button_to_stop_activity(button)
            self.change_task_menu_to_stop_activity(task.get_id())
        else:
            self.change_button_to_start_activity(button)
            self.change_task_menu_to_start_activity(task.get_id())
