Description

I have created a module in which there is a need to create a New Print Composer and add to Composer some rectangles, setting them style by setShapeStyleSymbol. Everything works well and the rectangle is created with the necessary style. But when you try to close down QGIS, it does not close down, or causes crash (Project/ Exit QGIS).
I tried it in two versions 2.8.2, 2.10.1. Windows 7 64bit, Windows 10 32bit, Windows XP 32bit.

For example Python Console code:

@
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from qgis.core import *

self = qgis.utils

Mlayer = QgsVectorLayer("Polygon", u"Test_Polygon_Layer", "memory")
QgsMapLayerRegistry.instance().addMapLayer(Mlayer, True)

symbol = Mlayer.rendererV2().symbols()[0]

newco = self.iface.createNewComposer()
newcomp = newco.composition()
newcomp.setPlotStyle(QgsComposition.Preview)
cshape = QgsComposerShape(10, 10, 7, 4, newcomp)
cshape.setItemPosition(10, 10)
cshape.setShapeType(QgsComposerShape.Rectangle)
cshape.setUseSymbolV2(True)
cshape.setShapeStyleSymbol(symbol)
newcomp.addComposerShape(cshape)
print ''

Try cloning the symbol. Change:

symbol = Mlayer.rendererV2().symbols()[0]

to

symbol = Mlayer.rendererV2().symbols()[0].clone()
