QAbstractListModel crashes on endMoveRows() (ASSERT: "!this->isEmpty()")

Hey,

when using beginMoveRows() and endMoveRows() of QAbstractListModel, endMoveRows() causes the program to crash in debug mode.
The attached code should demonstrate the crash (only debug mode of course).

Following error is thrown:
Debug Error!
Program: ...for_Desktop-MSVC2010Qt_SDK_Debug\debug\ItemMoveTest.exe
Module: 4.8.0
File: global\qglobal.cpp
Line: 2232
ASSERT: "!this->isEmpty()" in file c:\iwmake\build_vs2010_opensource________________padding________________\include\qtcore\../../src/corelib/tools/qstack.h, line 68

This happened to me in some different situations.
