Bug Description

Ubuntu 16.10 x64

 * Install kaffeine (sudo apt install kaffeine)
 * Search for kaffeine in the dash (Alt+F2 then type 'k', 'a', 'f'...)

Actual result: kaffeine displayed icon is a generic icon, not the icon it is supposed to use.
Expected result: the icon which path is: '/usr/share/icons/hicolor/scalable/apps/kaffeine.svg' is displayed instead

 * Launch kaffeine
 * Look at kaffeine icon that appeared in the launcher

Actual result: the displayed icon is a nautilus directory icon
Expected result: the icon which path is: '/usr/share/icons/hicolor/scalable/apps/kaffeine.svg' is displayed instead

I rebooted the computer, thinking that a cache update was missing.
I also reinstalled kaffeine with apt install --reinstall
The symptoms remain in both cases.

It appears that installed applications usually provide png icons, located in '/usr/share/icons/hicolor/WxH/apps' (where WxH is the size of the image). But in the case of kaffeine, it only provides a svg icon.

From what I've been reading, that situation should be supported. In fact, if I change kaffeine .desktop file to make the icon path absolute, it works:

Open a text editor as root and open the desktop file: /usr/share/applications/org.kde.kaffeine.desktop
Find that line: Icon=kaffeine
Change it to: Icon=/usr/share/icons/hicolor/scalable/apps/kaffeine.svg

It seems that just a small thing is missing in Ubuntu to provide full svg icon support.
