Applications 15.12 have been introduced in experimental a little bit more than
2 month ago: I'm very keen about seeing them in testing or even in sid,
because this version would allegedly fix that bug:
which is preventing me, and everyone else following testing I believe, to have
pdf preview in Dolphin for many month now.
I might be mistaken though about that actually being the reason I don't have
preview because testing version (of kdegraphics-thumbnailers) isn't really
15.08 designated as being the culprit...
Anyway, are there issues preventing 15.12 from moving to sid, as it is the
case for Plasma 5.5?
By the way I did install kdegraphics-thumbnailers 15.12 from exp; I do now
have a list item which I can tick in order to have ps/pdf preview; actual
preview I don't have yet...
What I think is that if the package were in sid, more people would install it,
and I would have more chance to see my issue fixed.
