            Bug ID: 345517
           Summary: KMail crashes on exit
           Product: kmail2
           Version: 4.14.1
          Platform: Debian stable
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: bugs at humanleg.org.uk

Application: kmail (4.14.1)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.0 (jessie)

-- Information about the crash:
- What I was doing when the application crashed:
Closing KMail.
- Unusual behavior I noticed:
KMail had been continually complaining that the "KMail folders" were "broken"
because it couldn't write to one of the directories. I couldn't see why it
couldn't write to the directory.
- Custom settings of the application:
Had just upgraded an old kmail1 setup with disconnected imap folders.

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