Version: (using KDE 4.2.2) OS: Linux Installed from: Debian testing/unstable Packages Since upgrading to Kmail in KDE 4 i couldn't sign and verify email anymore. Signing works randomly during any kmail (kontact, in fact) session, and i got or "General Error" message upon signing or "No key has been configured for this identity" message (actual message is longer, and i have it in italian, so it maybe not the exact translation). Sign verify fails with the "Not enough information to validate the sign" (again, it's a translation from the actual italian message). Upon opening identity configuration an error message box appears: "An error has occurred while retrieving keys from the backend. General error" (translation from italian). Same error if i create an new user and generate a new keypair. In KDE 3.5 kmail it's ok.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
