Bug 226613

Application: kmail (1.13.0)
KDE Platform Version: 4.4.00 (KDE 4.4.0) (Compiled from sources)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-thinkpad x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I wanted to send a mail. My SMTP password is in KWallet. KWallet was running and still had the password cached, as I had started KMail just a few minutes ago, and it used my IMAP password, which is also in KWallet. So when sending the mail, KMail asked for access to the wallet, and I granted it access “once”. Then KMail crashed.

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