Description
Both gdal algorithms of gdal won't open in processing due to this python error (QGIS compiled from source):
TypeError: 'NoneType' object is not subscriptable
Traceback (most recent call last):

[processing] Fix rasterize dialog openning
Fix #16061
Do not pass in getConsoleCommand just to get commandName for shortHelp.
This avoid errors with non initialized parameters.
[processing] prevent Python error if input layer is not set (fix #16061)

Just a small note. This error thrown only if algorithm opened with empty project, if there is a vector layer loaded all not error is displayed.

mmm.. on my machine I get the same error also with layers in the toc and with or without any project opened
#5
Updated by Giovanni Manghi over 7 years ago
I also see the error regardless the project is empty or not.

Reopening this , running current 2.18(.13) head ( QGIS code revision ce11ebb48b ) here.
Having exact this error message in 'Rasterize (vector to raster)'
Printing out the 'arguments'-string of share/qgis/python/plugins/processing/algs/gdal/rasterize.py" I have:
['-a', u'1', '-ot', 'Int16', '-of', 'GTiff', '-tr', u'1', u'1', '-a_nodata', u'1', '-co COMPRESS=JPEG', u'-co JPEG_QUALITY=1', '-co BIGTIFF=YES', u'1', '-l', None, u'1', u'dummy']
Looks like this is the inLayer? Which in my case is not yet choosen (as it is the first time I open the dialog, maybe not even with layers in my legend...)?
