Version: 1.2.5 (using KDE KDE 3.5.7) Installed from: Ubuntu Packages OS: Linux Kubuntu Feisty Fawn with KDE 3.5.7, Kontact Mail 1.2.5 Severe data loss: I have configured Kontact Mail/KMail with a POP3 server and downloaded intitally 2099 messages. After deleting some newly arriving messages, Kontact rendered mails which where clicked on in the mail list view to: >> Sender Unknown, No Subject, 1970-1-1 << I could not recover these mails. (also not by copying them to a new folder). After restarting Kontact Mail the problem prevailed. see also: https://bugs.launchpad.net/ubuntu/+source/kdepim/+bug/50039
