+   the Python objects added to the desktop. This causes a small memory leak (the wrapper around desktop
+   object is never garbage collected) but since this object contains only references this is not
+   considered a big problem. With versions < 4.15, it seems that this reference was kept implicitly.
+   No proper solution was found for versions between 4.15 and 4.15.4 (included), so those versions
+   should not be used to compile GUI module.
