Error in running the plugin

[pcav]

I'm getting an error by simply selecting two points ad adding a

dimensioning:

Traceback (most recent call last):
File "/home/paolo/.qgis2/python/plugins/dimensioning/dimensioning.py",
line 133, in calculateDimensioning
tools.utils.addGeometryToDimensionLayer( f, "main" )
File "/home/paolo/.qgis2/python/plugins/dimensioning/tools/utils.py",
line 35, in addGeometryToDimensionLayer
QgsMapLayerRegistry().instance().addMapLayer(vl, True)
TypeError: qgis._core.QgsMapLayerRegistry cannot be instantiated or
sub-classed

I also get another error, I do not know if related:
2016-06-14T08:59:03 1 Traceback (most recent call last): File "/home/paolo/.qgis2/python/plugins/dimensioning/dimensioning.py", line 83, in calculateDimensioning pt1.setX(self.p1.x()) AttributeError: 'NoneType' object has no attribute 'x'

Remove the brackets in utils.py line 35 to:
QgsMapLayerRegistry.instance().addMapLayer(vl, True)

Then the plugin works, but there are still issues with the spatiallite db and the distance isn't stored in the database as i understand it.
