Bug 284169

Application: kontact (4.7.2)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
1. I imported my old mail from kmail > 100000 entries
2. Then I right clicked folder by folder choosing "mark all as read" (The icon changed into a circlic process indicator)
3. After some time of heavy disk access all choosen folders showed no unread mail any longer
4. One imported folder was still untouched though (~800 unread mails)
5. I clicked on that folder => crash happend

- Unusual behavior I noticed:
I switched on kernel block dump locking with
echo 1 > /proc/sys/vm/block_dump

In the log (/var/log/kern.log) I noticed akonadi constantly and frequently accessing the disk. Also the whole app seems to be slow after the import of the old mails.

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