    Description

      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.
