K3b crashs if click on bookmarks with no existing path

how to reproduce
================
1) i added the bookmarks to dolphin (see screenshot)
2) after that, i have changed the volume labels, so it is mounted with another path than the old one
3) open k3b -> dialog 'The file or folder .. does not exist' ! -> click OK
4) when i click in K3b window on this old bookmarks with no existing path, k3b crashs
(interesting think is, that dolphin opens it without crash)
