Thanks.  Way too many people don't include even that basic level of info.

You are very likely correct, as kipi-plugins (here on Gentoo ~amd64 
running the kde overlay) installs these service files:

/usr/share/kde4/services/kipiplugin_acquireimages.desktop
/usr/share/kde4/services/kipiplugin_advancedslideshow.desktop
/usr/share/kde4/services/kipiplugin_batchprocessimages.desktop
/usr/share/kde4/services/kipiplugin_debianscreenshots.desktop
/usr/share/kde4/services/kipiplugin_dngconverter.desktop
/usr/share/kde4/services/kipiplugin_facebook.desktop

Try checking your kipi-plugins package to see if it installed them and 
where.

Then try stracing gwenview to see where it's looking for them, with a 
command such as this (-f says follow forks, -eopen says report on file-
open attempts only, 2>&1 redirects STDERR to STDOUT so it can be grepped, 
ENOENT = error, no entry, can't find the file):

strace -feopen gwenview 2>&1 | grep ENOENT

That's still likely to produce a whole slew of output, but you can 
further pipe it to grep -v to remove stuff that looks uninteresting (-v 
reverses the grep, showing only lines that do NOT contain the search 
term).

Eventually you should be able to figure out where it's looking, and 
create symlinks or some such, as necessary (plus file a bug with slack, I 
imagine).

If the package doesn't include those files at all... well, I guess I 
could try sending a tarball.  They're not huge.  (Mostly they're name and 
comment lines in dozens of different languages, but there's a few real 
operational lines too.  It doesn't appear that they include path or 
version info, so any copy you can find should work, and the symlinks 
should stay working across versions as well, as long as the package 
continues putting them in the same place and the apps continue looking 
for them in the same place.
