Brian G reported a new bug.

Summary
-------

Application aborts segmentation fault 11 both 3.12 and 3.13

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

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

When I configure an application to use the enhanced dialogs gb.form.dialog if I open a Select directory dialog, then populate a combo box.
When I click the drop down for the combo box, boom seg fault.

I have included a small app which demonstrates this happening. I ran it on mint 19.2 and pi 4 buster both have the same crash. 
When i removed the gb.form.dialog the issue goes away. but the selectdirectory is more ugly.

I am trying to build on mint 19.2 so I can track it down more. If you already know why please let me know!

The system info is from one of the mint 19.2 system followed by the one from pi 4 buster
