Application: kmail (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0 (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.2.6-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

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

Kmail crashed after I marked message in IMAP Inbox folder as spam and switched to other message to view its content. In a status bar there were showing something like Filtering 1 message from 1 and after crash handler started I found Kmail asking for conflict resolution twice.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
