            Bug ID: 295880
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Crash when calling up "configure kmail" from menu bar
    Classification: Unclassified
                OS: Linux
          Reporter: blizzz at arthur-schiwon.de
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

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

Already using 4.8 the "akonadi_mailfilter_agent" and "akonadi_nepomuk_feeder"
started to run amok. That means,  they take 100% of CPU and memory consumption
increases rapidly, leading to a swapping system. The same after upgrading to
4.8.1. It always happens after system boot and restarting Akonadi via
"akonadictl restart".
In this case, I killed all those processes. After finding out, that I cannot
sent mail without "akonadi_mailfilter_agent", i restarted Akonadi and killed
all the "akonadi_nepomuk_feeder" processes (Nepomuk is disabled, btw, because
of the wrong hope that this process does not make problems then). I tried to
sent the mail trice, but it did not work as the "akonadi_mailfilter_agent" of
course was running with 100% cpu and eating RAM. So I killed this and the
following "akonadi_mailfilter_agent" processes. After that, I wanted to call up
the 'Configure KMail' dialog via menubar, then Kontact crashed.
