Version: KMail 1.9.7 (using KDE KDE 3.5.8) Installed from: Gentoo Packages Compiler: gcc (GCC) 4.1.2 (Gentoo 4.1.2 p1.0.2) OS: Linux This day I had to shutdown my xserver during a running kde seesion by pressing ctrl+alt+backspace. After this in the restarted kde session kmail/kontact shows the behavior that all mail I try to read got blank and are displayed like this: Subject. No Subjec Sender: unknown Date: unkown I had to restart the system to stop kmail destroying emails when I click on them.
Created attachment 22956 [details] screen shots shows the destroyed emails
Probably only the index files got corrupted during the crash. Try to delete your index files (~/.kde/share/apps/kmail/mail/[..]/*index*). This is probably also a duplicate of bug 121272. *** This bug has been marked as a duplicate of 121272 ***
