Description

When I edit "Providers option" or I add a new model/script to the Processing list, i receive "Maximum recursion depth exceeded while calling a Python object" (see attachment), and so I have to kill the QGis process.

This error appears in QGis version 2.18.18 and 2.18.19 (but not in 2.18.17)

Subject changed from Maximum recursion depth exceeded while calling a Python object to Maximum recursion depth exceeded after adding a model or script to the Processing algorithm list (since 2.18.18!)

It looks very similar to #18807, but that bug was introduced after 2.18.18. Hopefully that fix helped here as well.
Please test on 2.18.20 (to be released May 18, or you can compile 2.18 by yourself).

After #18807 Enabling/disabling algorithm providers as well as creating/removing preconfigured algorithms causes an infinite loop
It's the other issue introduced by c83261395476b62f6

I will propose a fix.
