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

I also see the error regardless the project is empty or not.

Reopening this , running current 2.18(.13) head ( QGIS code revision ce11ebb ) 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...)?

• priority_id was changed from Severe/Regression to Low
• regression was changed from 0 to 1
