            Bug ID: 312637
           Summary: Opening Kmail2 causes a subsystem to later crash
    Classification: Unclassified
           Product: Akonadi
           Version: 4.9
          Hardware: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: Mixed Maildir resource
          Assignee: kdepim-bugs at kde.org

                CC: krammer at kde.org

Application: akonadi_mixedmaildir_resource (4.9)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.10

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

I opened Kmail and got on with other work. A few minutes later a related system
generated this crash report. I have seen the same report before during normal
kmail usage, but would classs the crash as intermittent.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail Folders of type KMail Mail Folder
(akonadi_mixedmaildir_resource), signal: Bus error
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
