Why don't you remove it with `GLib.Source.remove()` ?

I am Sorry, I am not sure, how to do that. Is this Ok? ```` disable() { imports.ui.endSessionDialog.EndSessionDialog.prototype._sync = A; GLib.source_remove(this._timerId); imports.ui.endSessionDialog.EndSessionDialog.prototype._startTimer = B; } ````

Yes. That's ok but you should also check whether the timeout id exist. So, from your example, this is the correct one: ```js disable() { imports.ui.endSessionDialog.EndSessionDialog.prototype._sync = A; if (this._timerId) { GLib.source_remove(this._timerId); } imports.ui.endSessionDialog.EndSessionDialog.prototype._startTimer = B; } ```

I'm going to reject this one, please send it again once you fixed the timeout.
