Description
When a command has an error, and is ran as iterative, the underlying error is not handled gracefully, and returns:
Traceback (most recent call last):
File "/usr/share/qgis/python/plugins/processing/gui/AlgorithmDialog.py", line 238, in accept
if runalgIterating(self.alg, self.iterateParam, self):
File "/usr/share/qgis/python/plugins/processing/gui/AlgorithmExecutor.py", line 90, in runalgIterating
if runalg(alg):
File "/usr/share/qgis/python/plugins/processing/gui/AlgorithmExecutor.py", line 52, in runalg
progress.error(e.msg)
AttributeError: 'NoneType' object has no attribute 'error'

this is fixed in master

Looks like it is not backported...

Thanks. IMHO it is useful to backport it both to 2.14 and to 2.16 series.

Unsure whether it is the same error. Also running `SAGA:Clip raster with polygon` runs fine without iterative, but fails when iterating, with:

AFAICT iterating is broken now in 2.16, so I raise the severity.

in 2.18, no error is displayed, even when layers are not created.

If I understand correctly 2.16 will not receive updates anymore, so there is no sense to backport anything to it
