-- Information about the crash:
Kmail è bloccato: non riceve la posta, non mi consente di cancellare le email, non applica i filtri.
Dopo averlo chiuso, alla riapertura non ricompare l'icona nella tray area. Modificando le impostazioni per ripristinare l'icona nella tray area il prgramma crasha.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
