Backports on 14.04 (trusty) berak nepomuk subsystem

Hello,

I ran into a small issue with the ppa. I tried to file a bug report, but
I wasn´t able to.

 - Short Summary:

If I use the BACKPORTS on a TRUSTY installation, it breaks NEPOMUK
packages and uninstalls some of them. As a side effect dolphin won´t
show metadata or previews anymore in its "file overwrite dialog". For
example two images, if you try to overwrite an existing file.

 - What I did?

I booted a live usb stick with 14.04.5 and dolphin´s metadata display
worked as expected.  Then I included the backport-ppa into apt and ran a
package upgrade. Three nepomuk packages missed their dependencies on
libkdecore5/libkdeui5 (sticked to 4.13.3) which were now unavailable.
KDE itself got updated (4.14). These were libnepomuk4, libnepomukquery4a
and libnepomukutils4. They couldn´t be installed sanely again. I stopped
the display manager, removed the configuration files in user home,
flushed the kernel (disk) cache and restarted the session with the
updated KDE. Dolphin´s metadata display was broken.

 - What I expected?

The backport ppa would keep nepomuk infrastructure intact :)

 - Some thoughts...

I don´t know how hard it is to make it work again on KDE 4.14, but it
would be nice. On the internet I found reports related to KF5 (I´m
unsure if this still uses nepomuk as interface or baloo directly?).
Nevertheless in that case it had been solved last year.

Description-de: Nepomuk-Meta-Daten-Bibliothek
 Nepomuk aims to provide the basis to handle all kinds of metadata on
the
 KDE desktop in a generic fashion. This ranges from simple information
such
 as tags or ratings over metadata extracted from files to metadata that
is
 generated by applications automatically. RDF, the Resource Description
 Framework, provides the powerful basis to store and query all this
data.
 The goal is to categorize all metadata using clean ontologies to make
an
 automated handling and enrichment of the data possible.
