            Bug ID: 322333
           Summary: Mail filter crashed on manual apply
    Classification: Unclassified
           Product: Akonadi
           Version: 4.10
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: Mail Filter Agent
          Assignee: kdepim-bugs at kde.org
          Reporter: maarten at treewalker.org

Application: akonadi_mailfilter_agent (4.10)
KDE Platform Version: 4.10.5 "release 4"
Qt Version: 4.8.4
Operating System: Linux 3.4.47-2.38-desktop x86_64
Distribution (Platform): openSUSE RPMs

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

I added a new client-side mail filter, selected a range of emails in my inbox
and pressed Ctrl-J to re-filter the selected emails. Very soon after that the
crash handler dialog popped up.

Looking at the backtrace, this crash might not have been the original filter
that crashed, but the automatically restarted mail filter process after the
previous filter died. I get quite a lot of Akonadi automatic process restarts,
unfortunately, although usually it is akonadi_mixedmaildir_resource that has
problems, not akonadi_mailfilter_agent.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Mail Filter Agent (akonadi_mailfilter_agent), signal: Segmentation
fault
Using host libthread_db library "/lib64/libthread_db.so.1".
