Description

Under QGIS master, a simple processing model to merge three raster layers is now broken, fails by returning an error message. Log:

Algorithm simple merge starting...
Prepare algorithm 0: Merge
Running Merge [1/1]
Parameters: INPUT =None, PCT =True, SEPARATE =True
Failed
Error executing algorithm 0 'NoneType' object has no attribute 'split' See log for more details

The merge algorithm itself is working fine when used outside of a modelling process. It seems the INPUT parameter doesn't get compiled properly, i.e. it should be my list of rasters, not None.

I'm attaching the simple merge model here to ease debugging by developers. This used to work in earlier versions of QGIS, flagging as a regressing blocker.

Giovanni, by working you mean you try to execute the attached model?
