Application: kontact (4.6.1)
KDE Platform Version: 4.6.5 (4.6.5) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-gentoo x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
- What I was doing when the application crashed:

Again - it's running in a window in the background - no user interaction, simply running spam-filter and checking/moving mail from IMAP (to a local Maildir Trash folder if it's found to be spam). Again kmail2 crashes, this time with a new backtrace.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
