Crash QGIS almost every time

[uprel]

Tried to run QTiles with different combinations and it is very unstable. Almost every time crash QGIS. With simple point layer I manage to create directory structure and mbtiles. All other combinations crash.

I'm running QTiles 1.5.2.1 with QGIS 2.14.19 on Windows 10.

Before crash there was this error in QGIS console:

warning:C:/Users/uros/.qgis2/python/plugins\qtiles\qtilesdialog.py:238: DeprecationWarning: QgsMapCanvas.mapRenderer() is deprecated
			  extent = QgsCoordinateTransform(canvas.mapRenderer().destinationCrs(), QgsCoordinateReferenceSystem('EPSG:4326')).transform(extent)
			
			traceback:  File "C:/Users/uros/.qgis2/python/plugins\qtiles\qtiles.py", line 97, in run

Similar problem here with QTiles 1.5.2.1 and QGIS 2.18.13 on Linux.

I can render png to a directory but in the moment the tiles include a lot of features, QGIS crashes.

The error you mention is a warning and appears in the moment I click the Run button.
