I'm a software engineer at Tableau Software and we've discovered a bug in Dell's Backup and Recovery software that is causing any 64-bit application which uses the Qt5 core DLLs to crash whenever a Save or Open file dialogue is opened. We have been able to reproduce this behavior with an extremely simple application using just QT code:

#include
#include

int main(int argc, char *argv[])
{

QApplication a(argc, argv);
QFileDialog::getSaveFileName();

return 0;

}

This app was built in Qt Creator with the standard Qt 5.4.1 SDK for 64-bit MSVC2013.
