If i ssh to with

Code:
ssh -X user@ip dolphin
then i get this:
http://users.telenet.be/photo-memori...no%20icons.png

A workaround for that is installing qt5ct and use another icon theme.


But if i'm on ssh -X with dolphin and want open a txt file then opens kwrite or kate on the screen of the host computer.
not on the screen where ssh dolphin opened. this is on tumbleweed 20170707 20170730 (and not on leap 42.2)
where do i start to find out where the problem is, it happens with kwrite, kate, gwenview, okular, the info of copy files, .... (probly the hole plasma stuff)
