Bug 253054

Version:           CVS (using Devel) 
OS:                Linux

Akonadi applications display collections based on their mimetype. For example the KAddressbook only displays collections containing contacts and distribution lists. KOrganizer looks for events and todos.

The filtering is done by akonadi but there is a bug: The filtering works only if the collection in question is a top level collection or there is at least one top level collection with the correct mimetype.

With e.g. the groupdav resource this is not the case.

Configuration Examples:
1. Only iCal resource loaded
Resources: iCal
Works

2. Only groupdav resource loaded:
Resources: groupdav/calendar
Doesn't work

3. Groupdav and iCal resource loaded:
Resources: groupdav/calendar, iCal
Works.

Reproducible: Always

Steps to Reproduce:
Add a resource that provides non top-level collection with a matching mimetype and make sure it is the only one that matches. Then try to list this mimetype with the EntityTreeView.
For example: Set up the groupdav resource, make sure it is the only one providing contacts and open KAddressbook - it will be totally empty.

Actual Results:  
Empty model.

Expected Results:  
Model containing the groupdav resource.

I wrote a workaround and will upload it to the reviewboard after this bug report.
