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:
