Bug#800821: also needs service files

[Tim Colgate <debian@mettalogic.co.uk>]

Unfortunately quite a lot of paths have changed in the transition from KDE 4 to 5, and dolphin moved to KDE5 while konqueror seems to be still on KDE4:

$ konqueror --version
Qt: 4.8.7
KDE Development Platform: 4.14.12
Konqueror: 4.14.10

$ dolphin --version
dolphin 15.08.1

I found that in addition to dolphinpart.so, you also need to copy/link various service files:

/usr/share/kde4/services/dolphinpart.desktop -> /usr/share/kservices5/dolphinpart.desktop
/usr/share/kde4/services/kcmdolphingeneral.desktop -> /usr/share/kservices5/kcmdolphingeneral.desktop
/usr/share/kde4/services/kcmdolphinnavigation.desktop -> /usr/share/kservices5/kcmdolphinnavigation.desktop
/usr/share/kde4/services/kcmdolphinservices.desktop -> /usr/share/kservices5/kcmdolphinservices.desktop
/usr/share/kde4/services/kcmdolphinviewmodes.desktop -> /usr/share/kservices5/kcmdolphinviewmodes.desktop

While the following binary files need to be taken from a previous version of dolphin:

/usr/lib/kde4/dolphinpart.so
/usr/lib/kde4/kcm_dolphingeneral.so
/usr/lib/kde4/kcm_dolphinnavigation.so
/usr/lib/kde4/kcm_dolphinservices.so
/usr/lib/kde4/kcm_dolphinviewmodes.so
/usr/lib/libdolphinprivate.so.4

This worked for me, although I can't guarantee it's either a minimal or a complete setup.

Ofc, better to downgrade the dolphin package as you suggest and wait for it to be fixed properly.
