Review request for kdelibs and Peter Penz.


Summary
-------

When sorting by name KDirSortFilterProxyModel uses UDS_DISPLAY_NAME. The latter, however, is not unique. This results in strange GUI behaviour like swapping items. This patch makes the model fall back to UDS_NAME to ensure a fixed sort order.
I also propose to backport it to 4.6.
