            Bug ID: 329063
           Summary: KMail crashes after quitting and restarting
    Classification: Unclassified
           Product: kmail2
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: sauravsgs at gmail.com

Application: kmail (4.12)
KDE Platform Version: 4.12.0
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

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

I had started KMail after logging into my system. The first time KMail starts
up correctly. Then I quit KMail and immediately after that I tried starting
KMail again but instead of starting, the application crashed right away. The
crash always occurs while trying to start KMail a second time in this way,
irrespective of what I was doing in KMail when I had started it the first time.
During the first run, there were no hangs, freezes or lags in my usage of the
application.

The crash can be reproduced every time.

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