QML debbugging brings up error message on closing Qt Quick 2 application

Steps to reproduce:

• start Creator with clean settings (Qt 5.2 kit should be setup automatically)
• create Qt Quick Application using QtQuick 2.0 (from New Project wizard)
• start debugging, don't stop the debugger by pressing 'Stop'
• click into the Qt Quick application (onClicked should call Qt.quit())
• application closes, debugger finishes and Creator brings now an error message 'Could not connect to in-process QML debugger.' (Retry, Cancel, Help)

Expected behavior:

• no error message box as debugging is done already (works fine using Qt Quick 1.1 Application)
