Spyder: Variable explorer crashes with bool dict

[cmfrantz]

Description

What steps will reproduce the problem?

A dict is created that includes a mix of strings and boolean values as the key. When trying to open it to inspect it in the Variable explorer, I get this 'Spyder has encountered an internal problem!' error.

Hi @cmfrantz,

Please update spyder to the latest version, where I'm unable to reproduce this one.

conda update anaconda
conda install spyder=4.2

Please let me know if this fixes your issue

I don't seem to be having this problem anymore. Thanks!
