Qt6 program crashes when activating the file dialog.

[hoream]

The same as [url]https://archlinuxarm.org/forum/viewtopic.php?f=15&t=17122[/url] It can be reproduced with the following simple program.

[code]#include <QApplication>
#include <QFileDialog>
#include <QMessageBox>

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

QString fileName = QFileDialog::getOpenFileName(nullptr, "Open file", "", "All files (*)");

return app.exec();
}[/code]


[code]Thread 1 "FileDialogTest" received signal SIGSEGV, Segmentation fault.
