The bug also affects e.g. filelight. This was initially a bug in KService (https://bugs.kde.org/show_bug.cgi?id=344614), but then Dolphin changed the implementation and moved to a KNewStuff menu. So now this could be a bug in KNewStuff.
I'm adding Gregor (who added this feature) in CC, he might know more.

Thanks for the bug report.

Your accidental discovery of the feature tells me that the feature should be presented in a more obvious way.

To analyse the problem I did this to see if and where the .desktop file is installed:

$ rpm -ql partitionmanager5

/opt/kf5/bin/partitionmanager
/opt/kf5/share/appdata/org.kde.PartitionManager.appdata.xml
/opt/kf5/share/applications/org.kde.PartitionManager.desktop
/opt/kf5/share/config.kcfg
/opt/kf5/share/config.kcfg/partitionmanager.kcfg
/opt/kf5/share/icons/hicolor/scalable/apps/partitionmanager.svg
/opt/kf5/share/kxmlgui5/partitionmanager
/opt/kf5/share/kxmlgui5/partitionmanager/partitionmanagerui.rc


In line https://lxr.kde.org/source/frameworks/knewstuff/src/kmoretools/kmoretoolspresets.cpp:133 you see

dict.insert(_("disk-partitions"), { _("gparted"), _("org.kde.PartitionManager"), _("disk") });

This means a desktop file with name "org.kde.PartitionManager" is expected which is the case in my case. But on my maschine the KDE PartitionManager is also shown as "not installed".

So at first glance I cannot see the problem's cause.

Maybe the cause is that partitionmanager is now the KF5 version which is located in the /opt/kf5/... directory?

The "Name" in the desktop file has changed (see https://lxr.kde.org/source/frameworks/knewstuff/data/kmoretools-desktopfiles/org.kde.PartitionManager.desktop ("Name=KDE Partition Manager") vs. the installed one ("Name=KDE Partition Manager/KF5")) but this should not be the cause.

I'd say let's move this to KNewStuff, since it's where this menu is created.

On my system partitionmanager is installed into /usr and it is still listed as not installed.

P.S. I also didn't know about this hidden feature in dolphin before seeing this bug.

I'm running Manjaro, an Arch based distro, and just as with Andrius Štikonas both desktop files (org.kde.PartitionManager.desktop from partitionmanager and from knewstuff) are locate at /usr/share/... and both have Name=KDE Partition Manager.

*** Bug 374683 has been marked as a duplicate of this bug. ***

The desktop file name changed to lower case from
/usr/share/applications/org.kde.PartitionManager.desktop to
/usr/share/applications/org.kde.partitionmanager.desktop

I'll provide a patch.

Gregor, any progress with comment #7?

The patch is ready at https://phabricator.kde.org/D7130. Someone needs to have a final look and give a Ship it.

KMoreTools: Update and fix desktopfiles

Summary:

Updates to KMoreTools:
- add minor code comments and update developer README
- update desktop files including fix for PartitionManager and KDiskFree
- add a script to easily update the desktop files
- add FSearch and AngrySearch to search tools
- add new grouping "screenrecorder" with Peek and Simples Screen Recorder
- add new grouping "mouse-tools"
- add new grouping "font-tools"
- add new grouping "language-dictionary"

The change is so big because of the update desktop files. The interface did not change.
