Dolphin 5 and getting new services

[O. Sinclair]

Dear all,

I regularly use some additional services in Dolphin. That they went 
missing on upgrade I can live with but:

When I try to add them using the installer I just get "installation 
failed". I like to use root-services now and then and also the encfs

I found out why preview was not working on a number of, well, 
previewers. After installation of say mpegthumpnailer you have to run 
this command, the bug is documented:
sudo ln -s /usr/lib/x86_64-linux-gnu/plugins/* 
/usr/lib/x86_64-linux-gnu/qt5/plugins/

Can be good to know.

But on the "adding services to the menu", anyone have an idea? Searching 
the web has not come up with anything.

kind regards,
Sinclair
