Icons for some applications are missing. In my case there isn't icon for internet browser and kate/kwrite. The icon for the internet browser appears sometimes but not always. Icon for kate/kwrite never appears. Here you are a screenshot with the problem:
Steps to Reproduce:
1. Start Plasma 5.7
Icons for some applications are missing.
There should be icons for programs in taskbar.
1. xprop outout for the KWrite window
2. the outout of: which kwrite
3. The name and location of KWrite's .desktop file on your system
Here you are, thank you:
2. mozo@mozo ~]$ which kwrite
3. I don't use .desktop file for kwrite. I use it only from context menu like right button Create->New File and Open with->kwrite/kate.
#3 is still important though, because it's involved in the icon-finding code
#1 doesn't work for me, apparently I need some sort of decryption key - can you use http://paste.kde.org/?
I don't know what to do for step 3. Tell me and I'll do it :)

This sounds very much like the problem that I have seen for several months now. However, today I looked into it and narrowed it down to the configuration file
The problem seems to be the section
which carries the index 32 [Containments], but is located before an entry with index .
I see this being automatically fixed when unlocking plasmoids and logging out and in again: Entry 32 is then moved to the end of the file with a new index and the icons are visible again.
There must be something else that I am missing. When starting plasmashell with locked plasmoids, some icons are missing. When starting plasmashell with unlocked plasmoids, everything is fine.
@Nick Stefanov @Martin Walch is this issue still relevant for you?
Nope everything working fine :)

No, I have not seen this problem for more than a year now. Looks like it is fixed.
