Nasty error bug: "error caught in notification handler"

[LZua]

Most of the time when I try writing code into a .py file, I get many error messages, where the first says something like:

[ncm2_jedi@yarp] error caught in notification handler 'on_complete [...]'

Needless to say, this renders the plugin unusable, since it makes editing code barely possible.

For example, in a file called "test.py" I have the following silly code:

# this is a simple Python script to illustrate my issue
import os
a = 2
for i in range(0, a):
    if i % 2 == 0:
        print(i/0)

# end of file ----------------- #

I simply open such file, then I try editing and get the error messages I send attached here.

Cannot reproduce. You could try a different version of jedi library.
