Bug 354715

Krazy  complains about the use of QLineEdit namedialog.ui from lskat:

But with KF5 this is not generally true any more (see comments on reviewboard). The  "Porting Notes" actually encourage the use of QLineEdit where the additional functionality of KLineEdit is not needed. (https://community.kde.org/Frameworks/Porting_Notes#General_2)
