QFile crashes on close(), when its FILE* handle is already closed

	// Open file handle
	FILE* pFile = fopen( "/tmp/hugo.txt", "w+");
	if( !pFile )
	{
		printf( "Error while opening file!\n" );
		return 7;
	}
	// Create QFile from file handle
	QSharedPointer<QFile> pSharedPointer(new QFile());
	pSharedPointer->open( pFile, QIODevice::WriteOnly );

	// close file handle
	fclose( pFile );

	// try to allocate the memory, where FILE* pointer points to
	DoSomethingWhichAllocatesMemory();

	// close QFile
	pSharedPointer->close();
