[QGIS-Developer] Error when saving Processing Script QGIS master

[matteo]

Hi guys,

I'm testing the the Processing script editor with custom python syntax.
It works super nice, but, after the scripts is saved and I want to close
the window this error pops up:

NotImplementedError: QgsProcessingAlgorithm.name() is abstract and must
be overridden

the script is correctly saved in the folder but is not loaded in Processing.

Some hints?

Thanks to all

Matteo
