Reading the default configuration for example. First the plugin gets
/usr/share/etc/xdg/xfce4/panel/launcher-7.rc as read location, but
when saving ~/.config/xfce4/panel/launcher-123456789.rc.

No you're wrong. When a plugin is properly removed and uses the config
path provided by xfce4-panel, the file is unlinked. In both the 4.4
branch and trunk. The config files left in your directory are 'custom'
config names (not known to the panel), or from plugins that crashed.
If you still don't believe me, search libxfce4panel for unlink ;).

Ok, no gerrors... I can live with that if the dbus interface provides them.
