I don't understand what you mean by this. Could you clarify it?

[ccordoba12]

Sorry, I understood it after seeing your screenshot. We'll fix it in our next version.

I can confirm this issue. Not sure why it happens for me and @leavor, but for sure we are not alone, and as the bug window appear as soon as I start typing, it's a critical bug.

I propose a quick fix in #14185, that I suggest to be released as soon as possible.

I was finally able to reproduce this bug (in 4.2.0).

1. Create a file containing

def f_g():
    pass

f_g()

2. put the cursor at the beggining of line f_g()
3. type _, _ ; the error should pop when writing the last _

And now I'm able to reproduce it, I withdraw what I said about criticality, it's a definitely not a critical bug.
