Issue 14 example qt-router exit error?

cxq2003

Issue 14 "Integrating Ice with a GUI: Part III" supplied an example "qt-router", and I successfully compiled and run it under qt 4.5 with visual studio 2003 on windows xp sp3 ,see attach file "interface.png", but when I close the qt-router main window, an error appeared, see attach file "errInfo.png", the full project see attach file "qt-router.zip".

How could I avoid the error? Was the problem brought by qt 4.5?

Fixed! I mixed the debug and release version .
