When exporting a model as script, vector outputs from intermediate algorithms appear as None parameter in corresponding processing.runalg call.
Here is the exported script:

@##Save Selection=name
##input=vector
##selection=output vector
outputs_QGISSELECTBYEXPRESSION_1=processing.runalg('qgis:selectbyexpression', input,'TRUE',0,None)
outputs_QGISSAVESELECTEDFEATURES_1=processing.runalg('qgis:saveselectedfeatures', outputs_QGISSELECTBYEXPRESSION_1['RESULT'],selection)@

This however causes the script to fail, because algorithm 'qgis:selectbyexpression' does not need an output parameter in its .runalg call.
Here is the Console Message after running the script:

@error: Wrong number of parameters
ALGORITHM: Select by expression
LAYERNAME
EXPRESSION
METHOD
RESULT @

After having manually deleted the output parameter 'None', everything works as expected.
We experience the same issue with the following algorithms:

'qgis:selectbyattribute'
'qgis:selectbylocation'

as well as algorithms from user scripts.

QGIS 2.14.3
Python 2.7.9
Qt 4.8.6
