Bug 220105

Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.4 (KDE 4.3.4) "release 2"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
set kmail to automatically check check for new mails every x minutes -> look for mail in IMAP-inbox (I have 2 of them active) -> close internet connection -> wait for timeout-notification (if you click "Get Mail"-button after disconnecting, kmail doesn't crash here) -> clicking OK crashes kmail (probably bug 191589, but the CrashReporter shows only duplicates of this, not 191589 itself)

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