Here are some typos fixes in Italian translation of dconf-editor.
At the time of writing, they're contatined at the string starting at this address: https://git.gnome.org/browse/dconf-editor/tree/po/it.po#n708

This is the current state of the string:

#: editor/dconf-window.vala:132
msgid "Thanks for using Dconf Editor for editing your settings!"
msgstr ""
"Grazie per usare Editor dconf per modificare la proprio configurazione."

and this is the proposed translation, including some fixes and a modification proposal for a better Italian translation:

#: editor/dconf-window.vala:132
msgid "Thanks for using Dconf Editor for editing your settings!"
msgstr ""
"Grazie per aver scelto Editor Dconf per modificare le tue impostazioni!"
