Account is configured to a) use PGP-MIME b) always sign, c) sign on reply to signed messages. If pgpinline module is loaded and a PGP-inline signed message is replied, then compose privacy menu is set to use PGP-inline to sign, against account preferences. If I reply to a unsigned, or PGP-MIME signed message, then PGP-MIME is correctly selected. If pgpinline is not loaded nothing of this happen, as only PGP-MIME can be used. I think account preferences should be respected instead of sender preferences.
