Warning: QDialog::exec: Recursive call detected

A strange error message, when launching qgis from terminal in gnome.
The message is printed when we click on plugin icone

Warning: QDialog::exec: Recursive call detected

I suspect it is because we use the click on icon event to create the plugin the first time

I think maybe our problem is simpler than that.
maybe from obscur reason the plugin GUI get created several time, even when it already exists.
It feels more like a design error than a race condition error.
putting a singleton would work too, but it could be better practice to review the code to correct the primary architecture problem instead
