Wow :(
A race condition was fixed in master, and backported to release branch... but incompletely!
15.8.2 got released in this broken state.
I just completed the patch, available in git "Applications/15.08" branch, let's see now how to distribute / propagate this fix to users...
Sorry for that poor situation,

The icons do not appear in Unity, but they show up if you are in Plasma Desktop.

Same version of KDENlive with the same source file. I just logged out of plasma and logged in to Unity, I didn't even reboot, and now the icons do not appear.

Just an info to whoever is subscribed to this bug: this problem does not occur on the kdenlive version of ppa:vpinon/kdenlive-testing - and it also has not crashed yet as I have tested, whilst the official ubuntu wily version crashes almost every time I am doing or selecting a title clip (shame on you, canonical! This software should not be unstable, you should be more diligent on ensuring stability for your users; the fact that a voluntary-compiled 'testing' version of the same software works better than yours is testimonial to your sloppy testing procedure. Or maybe you are bad in getting feedback from your users, my own bug requests are left unattended for a long period).

@ patola: It's always better to quote the public adress of the ppa in addition, since things may change:

Thanks Patola, I go to try the PPA vpion. I install UbuntuStudio 15.10 and kdenlive not has icons, however dolphin not has icons I don't understant why
