KeePass2 : Plantages fréquents sous Ubuntu 26.04

Lorsque qu'on tente d'ouvrir un nouveau fichier et qu'on modifie les options d'affichage de la fenêtre Open Database File(vues via les boutons, ou affichage des fichiers cachés via le menu contextuel), l'application s'arrête.

Les journaux indiquent :
