Comment 1 Patrick Silva 2020-04-24 14:02:08 UTC 
I followed the steps above with a new user account.
Once the wi-fi connection is stabilished and its password is saved, the crash is no longer reproucible.
Comment 2 Nate Graham 2020-04-24 17:58:01 UTC 
Hmm, cannot reproduce, even when I am asked to enter a password.
Comment 3 Patrick Silva 2020-04-29 12:08:37 UTC 
Currently Plasma crashes when I connect or disconnect a wi-fi network even if its details are not visible. I'm not sure if it is the same backtrace or not.

This looks like the plotter crash :/
Comment 5 Nate Graham 2020-05-14 18:58:17 UTC 
Which plotter crash?
