            Bug ID: 326042
           Summary: Another crash on Kontact (Kmail) exit
    Classification: Unclassified
           Product: kontact
           Version: 4.11.2
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: antonis+kdebugs at metadosis.gr

Application: kontact (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-32-generic x86_64
Distribution: Ubuntu 13.04

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

Pressed Ctrl-Q while kmailpart was active.

Again, it crashed, while following a slightly different code path than bug
288141 (the reason I'm filing a separate report).

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
