Willy RAETS reported a new bug.

Summary
-------

Project properties -> Environment -> Add error

Type             : Bug
Priority         : Medium
Gambas version   : Unknown
Product          : Unknown


Description
-----------

When I open the project properties of one of my projects and go to Environment -> Add I get an error:
[13] Null object
EnvChooser.Insert.239
(see added screenshot)

It happens in all my projects, not just a specific one.

I start Gambas3 with "env GB_GUI=gb.qt5 gambas3" to make procedure folding work on Mint 20 Mate
Installed Gambas3 from Gambas ppa
