Comment # 5 on bug 987900 from Sergio Lindo Mansilla

Reproducible on snapshot 20190201.

I get the same error message in journal as the attached log:

```
Feb 04 08:29:01 susetest sddm-greeter[2414]: QObject: Cannot create children
for a parent that is in a different thread.
                                             (Parent is
QGuiApplication(0x7fffe68e24d0), parent's thread is QThread(0x5635e7b0a1b0),
current thread is QThread(0x5635e7c46f50)
Feb 04 08:29:01 susetest sddm-greeter[2414]: QObject::installEventFilter():
Cannot filter events for objects in a different thread.
```

Do you need that I provide any other log?
