EXCEPTION in dispatchHoverEvent on Android

I get Exceptions in the log output whenever I touch the screen at any position.

W/Qt A11y (10924): EXCEPTION in dispatchHoverEvent for Accessibility: java.lang.reflect.InvocationTargetException
W/dalvikvm(10924): Stack overflow on call to interp (req=76 top=0x40257000 cur=0x40251328 size=24576 Ljava/lang/reflect/Method;.<init>)

I wrote some Widget based applications, all of them are affected and it happens on all real and virtual Android devices. Smallest program to reproduce:

#include <QApplication>
#include <QWidget>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QWidget* widget=new QWidget();
widget->show();
return app.exec();
}

The content of the project file is:

QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = test
TEMPLATE = app
SOURCES += main.cpp
CONFIG += mobility

I compiled with Qt 5.2.1 on Ubuntu Linux 14.04 using Android SDK 19 and NDK r9d.
