Problem Description

When opening a variable with complicated entries, Spyder crashes.

What steps reproduce the problem?

1. Unzip this zip file, inside is a *.spydata file SpyderIDEBug.zip
2. load the variables inside of this file into the variable explorer Now you should see a variable named “match” which is a list of dictionaries.
3. Open the variable “match” and open one dictionary

What is the expected output? What do you see instead?

It should show the entries of the dictionary, but Spyder crashes. Maybe it is because of this hexadecimal representation?

I had the same problem. I just updated spyder (conda update spyder) and now it works fine.

@dalthviz, it seems this is an issue with PyQt 5.12. Please check if there are references about something similar in the web.
