If statement without code block

https://code.qt.io/cgit/pyside/pyside-setup.git/tree/sources/pyside2/libpyside/globalreceiverv2.cpp

Lines 271-274: 

    if (m_refs.empty())
        Py_BEGIN_ALLOW_THREADS
        delete this;
        Py_END_ALLOW_THREADS

Either this is a bug and all 3 lines should be within a code block, or the indentation on the last two lines is wrong. Considering in PySide(1) the code is the same but without the Py_BEGIN/END_ALLOW_THREADS, I'm guessing it's the former.
