           Summary: KMail crash while selecting messagse
           Product: kmail2
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: graham at howlingfrog.com


Application: kmail (4.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.1-1.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

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

Selecting multiple messages in my Inbox by holding "shift" and clicking to
select multiple messages.

This release of KMail as provided by the Fedora-16 "kde-4.7.4" update crashes
far *more* than the previous 4.7.3 release did; it crashes for me several times
per hour (which is far cry from the "never crashed at all" that I used to
experience w/kmail pre-akonadi)

The crash can be reproduced some of the time.

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