KMail crashes very frequent like it was 15 years ago. Guys when You make KDE stable? :) It crashes: - on settings navigation, changing - mail sending/receiving, etc
We can improve it when we can reproduce the bugs. Please add exact configuration, steps to reproduce, and (for crashes) the backtrace you get from the KDE crash dialog.
Not reproducible in newest KMail. Crashed in Settings->Security tab for ex.
That was an openSUSE-specific issue, see bug 391336.
