Comment 1 Tony 2018-09-17 17:01:16 UTC 
Forgot to mention, the desktop launcher is a link to /usr/share/applications/firefox.desktop i added by right click the application dashboard and selecting "add to desktop".
Comment 2 Tony 2018-09-17 17:06:00 UTC 
..... copying said file into my Home and trying to do the same icon change crashes Dolphin only, not the desktop.
Comment 3 Christoph Feck 2018-09-19 00:54:00 UTC 
This might be caused by commit https://commits.kde.org/kiconthemes/fea52a4f204fd44d9a45e78a663964c326687e33
Comment 4 Tony 2018-10-11 02:14:47 UTC 
I don't get the crash anymore after updating to the latest packages of KDE unstable repository and snapshot for Tumbleweed. The speed while loading the icons noticeably varies though depending on the theme used.

Tested with different icon themes, breeze, breeze tumbleweed, elementary kde, oxygen, MacOSX one, El general and Infinity clear.

Crash is gone with this patch, all I get is icon picker, which is what I was expecting to see.
