-- Information about the crash:
- What I was doing when the application crashed:
stavo sfogliando velocemente cartelle e file nascosti (aprendo e chiudendo una cartella dopo l'altra, scorrendo lunghi elenchi di file per cercare manualmente risorse di un progetto Android da cancellare) all'interno delle cartelle .cache e .config della mia HOME.
Al momento del crash di Dolphin avevo aperto Firefox 88.0.1 (con diverse schede aperte e quella attiva aperta su un video di youtube) e Kdeconnect era attivo e collegato al cellulare.

- Custom settings of the application:
Visualizzazione dettaglio;
colonne visualizzate: Nome-Dimensione-Tipo-Modificato-Permessi-Proprietario-Gruppo utente;
doppio click per aprire il contenuto di un file;
file nascosti visibili;
ordinamento alfabetico/naturale senza distinzione minuscole/maiuscole;
mostra il numero di elementi nelle cartelle senza limite di profondità;
mostra la barra del filtro;
mostra la barra di stato

The reporter is unsure if this crash is reproducible.

-- Backtrace:
