           Summary: Crash of kmail when opening a draft
           Product: kmail2
           Version: unspecified
          Platform: Mageia RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: balcaen.john at gmail.com


Application: kmail (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.8.0
Operating System: Linux 3.2.2-desktop-1.mga2 x86_64
Distribution: "Mageia Cauldron"

-- Information about the crash:
- What I was doing when the application crashed:
Kmail crashed when i choose to open a previous mail in my draft folder.
Here i'm able to reproduce :
- answer to a previous mail, save it as draft
The draft folder here is on a gmail account.
- close kmail
- restart kmail & try to resume your draft mail, kmail will crash.
Once kmail is restarted  after the crash you'll get :
 - the mail kmail windows
 - a composer window with the content of the draft mail but in a 8 column
folder.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
