            Bug ID: 317055
           Summary: Removing resource from KOrganizer crashes KMail
    Classification: Unclassified
           Product: kmail2
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: dvratil at redhat.com

Application: kmail (4.11 pre)
KDE Platform Version: 4.10.1 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.8.3-201.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

-- Information about the crash:
- What I was doing when the application crashed:
I had KMail minimized and running. I removed an Akonadi resource (Google
Calendar resource to be specific) from KOrganizer and switched back to KMail.
At that moment KMail crashed.

The problem is apparently in some of the proxy models on top of ETM which does
not handle removed collections that don't have message/rfc822 mimetype.

This crash can be fixed by not loading non-email collections in ETM (see
https://git.reviewboard.kde.org/r/109259/). It's been requested in the review
though that the crash is properly investigated and the faulty proxy model is
fixed. hence this report.

Note that the crash can be reproduced on several other places in ETM (all of
them asserts) using the steps.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
