[Interest] Qt 5.5.1 QWebEngineView crash in debug mode

[ynon perek]

Hi All,

I recently upgraded to the new QWebEngineView with Qt 5.5.1 on a Mac 64bit.
When running with devtools (setting QTWEBENGINE_REMOTE_DEBUGGING
environment variable to a numeric value), the application crash on exit.

Is this a known bug? Any workarounds ?

This is the code I use:
#include <QtCore>
#include <QtGui>

#include <QtWebEngineWidgets>

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

    QWebEngineView view;
    view.load(QUrl("http://qt-project.org/"));
    view.show();

    return app.exec();
}

And the crash report is:
