Review request for Dolphin and Frank Reininghaus.


Description
-------

Fix wrong grouping of files (Esp. when sorting by file type)

Changes needed for master:
Add "const ItemData* parent = itemData->parent;" to retrieveData and remove the parent parameter from retrieveData.

Ideas for master:
Maybe use "void QtConcurrent::blockingMap ( Iterator begin, Iterator end, MapFunction function )" instead of a simple loop in setRoles, slotRefreshItems and createItemDataList.


This addresses bug 312014.

Testing
-------

Works for me.

Open a folder -> Sort by Type -> Sort by Rating -> Sort by .... -> Finally: Sort by Type (Files should be in the right file-type group)


Thanks,

Emmanuel Pescosta
