A gently reminder for this bug

Comment 2 Guido 2025-01-10 12:44:42 UTC

Su suggerimento di un utente su Reddit ho cancellato i file recently-used.xbel and RecentDocuments (both in ~/.local/share/). Questo ha risolto il problema.

Comment 3 Guido 2025-01-10 12:45:29 UTC

Sorry, in English: At the suggestion of a user on Reddit, I deleted the files "recently-used.xbel" and "RecentDocuments" (both in ~/.local/share/). This solved the problem.
