            Bug ID: 304324
          Severity: crash
           Version: 4.8.4
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Kmail & Kontact crash when moving an mbox via drag'n
                    drop
    Classification: Unclassified
                OS: Linux
          Reporter: carlo.tognetti at europe.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I imported an Evolution mbox tree into Kmail and everything was OK.
When moving some subfoldders folders from the imported sent subfolder to the
default sent folder, Kmail and Kontact sometimes crash.
I had multiple subfolders in the imported sent folder, sometimes moving them
goes on, sometimes not. I've already been able to move some sent subfolders
containing more than  2000 messages, that previously caused the crash. 

- Unusual behavior I noticed:
Just a few seconds before the crash, I've often seen the icons in the tray bar
(Volume, Screen, Clipboard, Devices, Network interfaces etc.) flickering fast,
and coming back stable just after the crash.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
