Description Nick Stefanov 2016-07-11 12:56:06 UTC

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:

Please attach:

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

Comment 2 Nick Stefanov 2016-07-12 09:30:58 UTC

Here you are, thank you:

1. https://mega.nz/#!3ARg1RDa
2. mozo@mozo ~]$ which kwrite
/usr/bin/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.

Comment 3 Eike Hein 2016-07-12 09:32:56 UTC

#3 is still important though, because it's involved in the icon-finding code

Comment 4 Eike Hein 2016-07-12 09:33:27 UTC

#1 doesn't work for me, apparently I need some sort of decryption key - can you use http://paste.kde.org/?

Comment 5 Nick Stefanov 2016-07-12 09:41:15 UTC

Sorry for that. Mega has changed their terms of use obviously. Here you are:

I don't know what to do for step 3. Tell me and I'll do it :)

.config/plasma-org.kde.plasma.desktop-appletsrc

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

~/.config/plasma-org.kde.plasma.desktop-appletsrc

The problem seems to be the section

[Containments][32]
activityId=00000000-0000-0000-0000-000000000000
formfactor=0
immutability=1
lastScreen=0
location=0
plugin=org.kde.desktopcontainment
wallpaperplugin=org.kde.image

[Containments][32][Wallpaper][org.kde.image][General]
height=1024
width=1280

which carries the index 32 [Containments][32], but is located before an entry with index [7].
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.

Comment 7 Martin Walch 2016-09-04 15:36:54 UTC

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?

Comment 9 Nick Stefanov 2018-02-28 09:40:16 UTC

Nope everything working fine :)

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