Application: kmail (4.7.4)
KDE Platform Version: 4.7.4 (4.7.4) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0.6-gentoo x86_64
Distribution (Platform): Gentoo Packages

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

I selected an account (legacy KMail Maildir) and all its subfolders. It contains over 100 000 emails. Then I rightclicked. It took about 5 minutes till the menu appeared. In that I then selected “mark all as read”.

After almost all folders showed no more unread mail (all but the one with subfolders), KMail crashed.

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