KDE apps fail start due to socket connect error

[Beeblebrox]

Hello. I'm using non-KDE desktop, but would like to use KDE apps. Starting KDE based apps throws out this error:

*  dolphin
KCrash: Application 'dolphin' crashing...
KCrash: Attempting to start  from kdeinit
KCrash: Connect sock_file=/home/rsbsd/.kde4/socket-rsbsd.me/kdeinit4_unix_0
Warning: connect() failed: : No such file or directory
KCrash: Attempting to start  directly
KCrash failed to exec(), errno = 2

* Has no effect:
mkdir socket-rsbsd.me && ln -s kdeinit4_unix_0 -> /var/tmp/kdeinit4_unix_0

* ~/.kde4 recursively owned by my user

* Some apps do start, but grunt:
$ okular

But above errors also existed on FreeBSD before I had switched to HBSD

* Installed KDE dependents:
x11/kde4-baseapps
graphics/kdegraphics4-mobipocket
x11/kdelibs4
deskutils/kdepimlibs4
x11/kf5-kded
x11/kf5-kdelibs4support
x11-toolkits/kf5-kdesignerplugin

Would appreciate any pointers where to look next
Regards
