Bug Description

When I try to save the actual xfce4-panel settings the save fails. When opening xfpanel-switch terminal, the following message appears when clicking to save:

Traceback (most recent call last):
  File "/usr/share/xfpanel-switch/xfpanel-switch/xfpanel-switch.py", line 221, in on_save_clicked
    self.save_configuration(name)
  File "/usr/share/xfpanel-switch/xfpanel-switch/xfpanel-switch.py", line 209, in save_configuration
    PanelConfig.from_xfconf(self.xfconf).to_file(filename)
  File "/usr/share/xfpanel-switch/xfpanel-switch/panelconfig.py", line 64, in from_xfconf
    pc.find_desktops()
  File "/usr/share/xfpanel-switch/xfpanel-switch/panelconfig.py", line 114, in find_desktops
    if self.check_desktop(desktop_path):
  File "/usr/share/xfpanel-switch/xfpanel-switch/panelconfig.py", line 88, in check_desktop
    bytes = self.get_desktop_source_file(path).read()
  File "/usr/share/xfpanel-switch/xfpanel-switch/panelconfig.py", line 129, in get_desktop_source_file
    return open(path, 'rb')
FileNotFoundError: [Errno 2] Arquivo ou diretório inexistente: '/home/usuario/.config/xfce4/panel/launcher-21/14294989537.desktop'

And the panel setting is not saved. When this happens, the buttons to save and close have no action when clicked.

Here is a image with the panel: https://i.imgur.com/7kuhAr5.png

First a quick description of the panel configuration: Every plugin on every panel is stored in a series of properties. Then, each panel has a list of plugins on that panel, which references the central list.

What has happened here is that somehow a panel has been deleted (panel-0), but the plugin settings associated with it have been left behind. However, the .desktop files for the launchers have been deleted. Launchers are not the only type of plugin which has been orphaned in this way, there are a few others. Every plugin with ID > 11 in the xml is an orphan.

I'm not sure how this happened. It doesn't seem to happen with the panel in 18.04 if you delete a panel.

In order to fix this I think panel-switch will have to check where every plugin exists somewhere on a panel, and if not ignore it (ie don't save it).

Oh and one other thing: the missing .desktops are dated from 2015 and this is an upgrade. Looks like the default panel configuration? Maybe this is a bug in an old xfce4-panel which is now fixed, but leaves behind broken config artifacts?
