            Bug ID: 302825
          Severity: crash
           Version: 4.8.4
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: KMail crashed when changing email identity draft
                    folder after database backend change
    Classification: Unclassified
                OS: Linux
          Reporter: devurandom at gmx.net
          Hardware: Gentoo Packages
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.4.4-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:
I changed the Akonadi database backend using the Akonadi KCM module (accessed
via akonaditray -> Configure...). Then I started KMail to reconfigure my email
identity's special folders. Changing the sent/drafts/templates folder of the
first identity worked without issues. When I changed the drafts (or sent? Not
100% sure) folder of the 2nd account, however, KMail crashed.

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