Requests the passphrase with a popup. As from GPGME 1.15.0, the loopback pinentry is functional when exporting secret keys. It works fine when the exact passphrase is provided. If it's a wrong passphrase, GPGME does not generate an ::Error, but the app crashes with 'free(): double free detected in tcache 2'. Hence, this patch cannot be committed to master. Status : dangerous Result : works and works not Reason : a wrong passphrase means a crash
