Application: kontact (4.10.1)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.8.3-103.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

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

I had tried to delete an email I had sent to a list where I was on the list.  Kmail seems to go into a funk when I do that, not showing the message as read, and flagging it as being in both the inbox and trash.  Kontact eventually crashes.

The crash can be reproduced sometimes.

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