Icons aren't applied to kde flatpaks.

[shellheim]

Hey!

Sorry for the terribly executed issue in #489. Here's a better report of what I found.

Icons don't get applied to flatpaks from kde. This not a problem with flatpaks in general on my system but only the flatpaks from kde.

Here's a few pictures. (sorry for the poor quality)

Arianna (an epub reader) and okular (a document viewer) from kde don't have their candy-icons applied but Libreoffice, which is a flatpak on my system, does.

Dolphin,kde's file manager, doesn't have it's icon applied but Fedora Media writer does.

This doesn't happen with GNOME's flatpaks, as can be seen with gnome-logs.

Workaround and it's limits.

There's a workaround, simply edit the app's .desktop file and change the 'Icon' field's value from something like org.kde.okular to document-viewer and then either clear icon cache or change the icons temporarily to something else and then change back.

Example

This doesn't work ❌

[Desktop Entry]
Terminal=false
Name=Okular
Name[de]=Okular
Name[el]=Okular
Icon=org.kde.okular

This does ✅

[Desktop Entry]
Terminal=false
Name=Okular
Name[de]=Okular
Name[el]=Okular
Icon=document-viewer

However, this ceases to work when the flatpak is updated and it's .desktop file re-written.

What I use

OS : Fedora 38
DE : KDE Plasma 5.27 Kernel Version : kernel-6.3.12-200.fc38.x86_64

it happen because the app as flatpak has a different name as the "official" app, i helped making a pull request with just a symlink to the original app-icon-name, pointing to the "new" name(that why the libre office has the icons, someone already patched it, but i guess anyone saw the kde icon) you can help too ;)

I knew that, but could you tell what exactly I can do, thanks for responding.
