Crash when exception thrown on QTreeWidget itemDoubleClicked

There is a bug when we throw an exception on slot connected to itemDoubleClicked signal (on a QTreeWidget).

I have reimplemented notify on QApplication to catch exception (like explained on documentation), when we double clic on an item : the exception is catched and printed out.
But if you click again (one time) on another item ==> crash.

I have tested on :

• Qt 4.8.2 with visual 2010 : NO crash
• Qt 4.7 with visual 2008 : NO crash
• Qt 4.8.2 / 4.8 with visual 2008 : CRASH

Of course, the bug happen only on Release and not in Debug mode.

You can try with attached files.

Regards.
