Version: 1.10.0 (using 4.1.00 (KDE 4.1.0), Kubuntu packages) Compiler: gcc OS: Linux (x86_64) release 2.6.24-19-generic After creation of pair of keys and selection in KMail setting keys to be used for both signature and encryption only encryption works fine. For signature I get all the time : Signing failed: Bad passphrase when the passphrase is not even asked for !
(No need to put that prefix in bug report summaries.)
