KActionMenu(const QIcon &icon, const QString &text, QObject *parent) failed to i18nc for Konsole https://twitter.com/xiangzhai/status/654138729271918592 when clicked the File menu on the top of Konsole, the New Tab failed to i18nc.

KActionMenu https://projects.kde.org/projects/frameworks/kwidgetsaddons/repository/revisions/master/entry/src/kactionmenu.cpp#L66 looks ok! is Qt5 bug?

KF5 Version: 5.15.0
Qt5 Version: 5.5.0

workaround patch for Konsole, but ... it is the huge work to change each KActionMenu:

Reproducible: Always
