+Date: Mon, 23 Sep 2024
+Subject: [PATCH] onboard: fix segfault when hovering over the keyboard
+
+Currently, if the mouse pointer is hovered over the Onboard keyboard, the application crashes with a segmentation fault.
+This is because the new_device_event function is not acquiring the GIL before creating a new object. This patch fixes
+the issue by acquiring the GIL before creating a new object. It also acquires the GIL before queueing the event.
+This patch is taken from the fix provided in the following link:
+https://github.com/void-linux/void-packages/commit/1be95325d320122efd5dedf7437839cfcca01f7a
