[Maya2015, Pyside] Fatal error crash on connecting selection model

I am converting tools to PySide for Maya2015, and everything works fine in this specific tool, except for these two lines of code which make Maya implode with a fatal error, not printing anything to console.


self.view.listJoints.selectionModel().currentChanged.connect(self.syncSelection)
self.view.listInfluences.selectionModel().currentChanged.connect(self.syncSelection)

Removing them makes the tool work, but it won’t sync selections so I can’t leave it out. Any ideas why Maya hates these lines?

Here’s the function I’m connecting too:


def syncSelection(self, proxyIdx, proxyPrevId):
	proxyModel = proxyIdx.model()
	if proxyModel:
		sourceIdx     = proxyModel.mapToSource(proxyIdx)
		sourcePrevIdx = proxyModel.mapToSource(proxyPrevId)

		if proxyModel == self._filterInfluenceModel:

			newIdx = self._filterJointsModel.mapFromSource(sourceIdx)
			sel = QtGui.QItemSelection(newIdx, newIdx)

			self.view.listJoints.selectionModel().select(sel, QtGui.QItemSelectionModel.ClearAndSelect)

		elif proxyModel == self._filterJointsModel:

			newIdx = self._filterInfluenceModel.mapFromSource(sourceIdx)
			sel = QtGui.QItemSelection(newIdx, newIdx)

			self.view.listInfluences.selectionModel().select(sel, QtGui.QItemSelectionModel.ClearAndSelect)
	return

Awesome, thanks.
