After Upgrade 3.16.0: Circular reference, Ctrl+C/Ctrl+V slow

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


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

After Upgrade 3.15.2 => 3.16.0
- [Ctrl+C,Ctrl+V] in the IDE became horrible slow (> 3 Seconds) !
- terminal warns a circular reference


What I did:
- a) Terminal bevore upgrade:
	xxx at yyy:~/Schreibtisch$ gambas3 --version
	3.15.2						=> ok
- b) [Ctrl+C,Ctrl+V] in the IDE pastes immediately 	=> ok



- Then upgraded from 3.15.2 to 3.16.0 in the terminal:
- - sudo apt-get --purge remove gambas3
- - sudo apt-get autoremove
- - sudo apt-get clean
- - removed ppa from sources.list
- - complete shotdown and system restart
- - sudo apt-get update
- - sudo add-apt-repository ppa:gambas-team/gambas3
- - sudo apt-get update
- - sudo apt-get install gambas3
- - sudo apt-get update
- - sudo apt-get upgrade


- After the upgrade:
-- Issue a): Terminal warns me a circular reference:
	xxx at yyy:~/Schreibtisch$ gambas3 --version
	3.16.0
	gbx3 [4106]: warning: circular references detected:
	gbx3:     3 Process

-- Issue b): [Ctrl+C,Ctrl+V] in the IDE takes > 3 seconds !

-- Issue c): Terminal:
--- gambas3
--- then open one of my programms and start it
--- terminal shows plenty of lines with:
(gambas3:6150): Pango-WARNING **: 11:09:12.577: Invalid UTF-8 string
passed to pango_layout_set_text()


- I tried this with
-- 2 different notebooks		=> Issue a) remains
-- 2 hosts, 2 guest (Virtualbox 6.1.20)	=> Issue a) remains

-- a new mini-Test-Programm	=> Issue b) disapears, a and c) remain
   (Cannot neither reproduce nor fix b) in my programms yet)
   (I also prefer to not send my 'programms') 


- What might  be of interest too:
-- Loaded components: gb .crypt .de .desktop .form .form.terminal .image
   .net .net.curl .qt4 .sdl2.autdio .term
   (I prefer loading .qt4/.qt5 expolicitely than using .gui.qt)  


By the way: Gambas Version 3.16 not yet in bugtracker-Combobox

Note: My programming level ist quite basic. So sorry if I missed something.
