I have Kubunut 15.04. When I add folder or something else to menu "places", this new position disappears after reopen Dolphin.
Others operation on menu "places", Dolphin memorizes.
Steps to Reproduce:
1. Add new places (link to folder) to menu "Places"
2. Restart Dolphin.
3. Your new position disappears.
It's the same with me here : Dolphin version 15.04.0
KDE Development Platform 4.14.7
running on Arch
