            Bug ID: 326899
           Summary: Kontact crashed right after start with heavy IO load
    Classification: Unclassified
           Product: kontact
           Version: 4.11.2
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: devurandom at gmx.net

Application: kontact (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.6-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
Kontact crashed right after the start. The window was grey for a long time
(probably due to the IO load making something unresponsive), and when it
briefly showed some content, Kontact immediately crashed.

- Unusual behavior I noticed:
The system was heavily loaded with IO tasks right after startup. (My HDDs are
slow, so Nepomuk and Akonadi startup creates very heavy load for a very long
time.)

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