           Summary: kmail crashed after clicking on a local folder
           Product: kontact
           Version: 4.7.2
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: deglerp at googlemail.com


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.
