Bug 236520

Application: kmail (1.13.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Upon the system startup, when Kmail tries to run automatically, once I introduce the password for the Kwallet account, Kmail crashes. The only way to start it is to close the wallet with KWalletManager and run Kmail again. I've checked that the first time the wallet is already closed.

The crash can be reproduced every time.

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