I assume Editor::marginClicked is a custom signal? How is it defined?

FWIW, as a workaround I added a definition of the headerDataChanged
signal to my model subclasses, like so:

    class CompletionModel(QAbstractItemModel):
        if PYQT_VERSION == 0x050b00:
            headerDataChanged = pyqtSignal(Qt.Orientation, int, int)
        def __init__(self, ...):

I'm not sure what happens when the model actually gets emitted (from
either Qt or PyQt), but at least that allows pytest-qt to connect to it
