crash when certain font is selected

When I select "Javanese Text" font via QFontDialog->getFont, my Windows PC crashes and QTCreator Application Output windows shows :

----------------------------------------------------------------------------

C:/Users/qt/work/qt/qtbase/src/gui/kernel/qevent.h(119): ASSERT: "!m_points.isEmpty()" in file C:/Users/qt/work/qt/qtbase/src/gui/kernel/qevent.h, line 119

t not only happens on "Javanese Text" but some others as well:

I printed out the Fonts on my system via 

 QStringList font_list = QFontDatabase::families(QFontDatabase::Latin);
 qDebug() << font_list;

Output:
