In alcune applicazioni si verificano dei crash nella libreria libcie-pkcs11.so; in particolare ho problemi con LibreOffice, che da diverso tempo crasha ogni volta alla chiusura:

A parte che non capisco il motivo per il quale LibreOffice carichi quella libreria, eliminandola il crash non avviene più e l’applicazione si chiude correttamente.
LibreOffice in teoria potrebbe essere usato per firmare digitalmente documenti attraverso le funzionalità dello standard (API) PKCS #11. Se si riuscisse a raggiungere questo livello con la CIE sarebbe meraviglioso.
Forse in qualche modo la libreria middleware .so per la CIE viene captata dal sistema operativo o da LibreOffice.
Sì, probabile. Appena crashato per la stessa ragione anche Okular, nello stesso modo:

Come hai settato i log della libreria? Ho assunto che ci fosse un config file in $HOME, ma nel mio caso in ~/.CIEPKI vedo solo un blob con estensione .cache.
Aggiungo ulteriori informazioni: il problema NON si presenta fino alla v1.4.1 del pacchetto CIE-Middleware; tutte le versioni successive, compresa l’ultima v1.4.3-3, sono affette.
