It also fails to launch a pause, if I force it.
Environment
SafeEyes (AUR safeeyes package, Arch/CachyOS)
Python 3.14
python-pywayland 0.4.19-1.1
KDE Plasma on Wayland
Problem
SafeEyes crashes on startup during plugin_manager.start() while loading the smartpause plugin:
File ".../safeeyes/plugins/smartpause/ext_idle_notify.py", line 29, in
from pywayland.protocol.wayland.wl_seat import WlSeat
ModuleNotFoundError: No module named 'pywayland.protocol.wayland.wl_seat'; 'pywayland.protocol.wayland' is not a package
Because this exception is unhandled, it propagates up through do_startup and the whole application fails to initialize — not just the smartpause feature. Breaks never fire, including forced breaks (safeeyes -t).
Root cause
Recent pywayland releases (confirmed with 0.4.19, built Aug 2025) changed how generated protocol code is laid out: instead of a subpackage per protocol with a submodule per interface (pywayland/protocol/wayland/wl_seat.py), each protocol is now a single flat module containing all its interface classes directly (pywayland/protocol/wayland.py, containing class WlSeat). The old nested import path no longer exists.
Fix
In safeeyes/plugins/smartpause/ext_idle_notify.py, change:
python
from pywayland.protocol.wayland.wl_seat import WlSeat
to:
python
from pywayland.protocol.wayland import WlSeat
This matches the current pywayland API and resolves the crash. Ideally this import should also be wrapped in a try/except (similar to the existing handling for ext_idle_notify_v1) so that a future pywayland/idle-notify API change degrades smartpause gracefully instead of blocking the entire app from starting.

@0x09AF Sorry, I did not notice your patch before.
