[Qgis-developer] TypeError: C++ type 'QgsFeatureIds' is not supported as a signal argument type

[//./\\-/_.\\]

Hi developers,

With OSX, QGIS 2.8.3 and higher, I found an error  what appears to be a 
regression (perhaps).
And with QGIS 2.12, the problem persists.

So, if you want to try to reproduce the error, open python console and try 
(with any active layer on editing mode):

>>> layer = iface.activeLayer()
>>> def listener(s, l):
>>>      print s, l

Then,

>>> layer.committedFeaturesRemoved.connect(listener)

Or

>>> from PyQt4.QtCore import QObject
>>> from PyQt4.QtCore import SIGNAL
>>> QObject.connect(layer, SIGNAL(r"committedFeaturesRemoved(QString, 
>>> QgsFeatureIds )"), listener)

It returns this error: “TypeError: C++ type 'QgsFeatureIds' is not supported 
as a signal argument type”

My English is so bad that nobody wants to answer me?
