QFileDialog::getOpenFileName crash in debug mode and not in realease mode

[Toutyx]

hello,

I use QFileDialog::getOpenFileName in my project.
When i execute my programm, this one crash in debug mode but not in release mode...

I have not idea why.

I use Qt 4.8.1 whith Qt-Crator 2.4.1 Windows 7 (64 Bit). My program is compiled in 32 bit.

QString qs_fichier = QFileDialog::getOpenFileName(0,tr("Fichier à envoyer"),
                                                      QString(),
                                                      tr("Ihm po Files (*.ihm_po)"));

QString qs_fichier = QFileDialog::getOpenFileName(0,tr("Fichier à envoyer"),
                                                      QString(),
                                                      tr("Ihm po Files (*.ihm_po)"));
