[Qgis-user] Processing: QGIS Crash with new processing script format, QGIS 3.6.1-SOLVED

[Stefan Giese (WhereGroup)]

Hi Harvard,
that's on the point - it works perfect now. Just in time, that I can use 
it next monday in my PYQGIS workshop. I think, that is tons easier to 
understand then the whole bunch of functions which you had to define 
before. Thank's again for the link and the work done on the manual. I 
have attached the changed script with the two processing algorithms

best regards
stefan
