F23: Extract here / Video Previews in dolphin

[Florian Sievert]

Hi,

and here a solution for these who are also missing the "Extract here"
within dolphin. Seems like the initial approach of symbolic linking
against the service desktop files provides by ark was basically the
right approach. However for some reason it seems that also the
"konqpopupmenuplugin.desktop" is missing for kf5. Thus the menu was not
appearing after all.

So in order to fix the issue, simply perform the following commands as root:
---
ln -s /usr/share/kde4/services/ServiceMenus/ark_*
/usr/share/kservices5/ServiceMenus
ln -s /usr/share/kde4/servicetypes/konqpopupmenuplugin.desktop 
/usr/share/kservicetypes5/
---
Then perform a "kbuildsycoca5" as user. I hope that I not having some
other "fixes" in place as it took me pretty long to get this running. So
would be nice if someone could confirm that the above description is
really enough to fix it. At least here the ark menu is there and seems
to be working fine now. Not sure what official package this might go in
order to fix this.

Best regards,
Florian
