  Target Milestone: ---

SUMMARY
When I run `dolphin .` in various directories, I get these error-messages in
the console (I don't know what caused them or what decides whether any message
or which message is displayed):

> kf5.kio.core: Invalid URL: QUrl("")

another time:

> org.kde.kcoreaddons: Error loading plugin "akregatorplugin" "The shared library was not found." 
> Plugin search paths are ("/usr/lib/x86_64-linux-gnu/qt5/plugins", "/usr/bin") 
> The environment variable QT_PLUGIN_PATH might be not correctly set
> error activating kdeconnectd: QDBusError("", "")
> ark.kerfuffle: Mimetype for filename extension ( "application/json" ) did not match mimetype for content ( "text/plain" ). Using content-based mimetype.
> Cannot initialize model with data QJsonObject() . missing: QJsonValue(string, "urls")

another time:

> org.kde.kcoreaddons: Error loading plugin "akregatorplugin" "The shared library was not found." 
> Plugin search paths are ("/usr/lib/x86_64-linux-gnu/qt5/plugins", "/usr/bin") 
> The environment variable QT_PLUGIN_PATH might be not correctly set
> error activating kdeconnectd: QDBusError("", "")
> ark.kerfuffle: Mimetype for filename extension ( "application/octet-stream" ) did not match mimetype for content ( "text/plain" ). Using content-based mimetype.
> Cannot initialize model with data QJsonObject() . missing: QJsonValue(string, "urls")

when I open Configure Dolphin->Services (this only occurs for Services, not any
of the other settings):

> User of KWidgetItemDelegate should not delete widgets created by createItemWidgets!
> User of KWidgetItemDelegate should not delete widgets created by createItemWidgets!
> [...]

when I click on "Download New Services" I also get the following above the
former messages:

> Rating cannot be superior to 100, fallback to 100.
> Rating cannot be superior to 100, fallback to 100.

I'm first interested in it apparently trying to start KdeConnect (it may get an
error as I run `sudo chmod -x /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd`)
as it may be the solution to:

I'm not sure if I ran Dolphin with sudo long ago. I have tried to install only
a few services.

I tried to install Scan with ClamAV (see https://www.opendesktop.org/p/998441/)
but installation failed both in the GUI and by running "sh install.sh" in
latest Debian (10) stable. No option to scan with ClamAV after running this.
Running mkdir /home/username/.kde/share/apps/solid/actions didn't help.

Where can I see a list of installed services and manage them?

STEPS TO REPRODUCE
1. Install use latest Debian stable with KDE and the latest Dolphin from its
repos
2. Run `dolphin .` in the terminal (multiple tries and/or wait in between
and/or navigate to Configure Dolphin->Services[->Download New Services])
3. See the error messages

OBSERVED RESULT
See the info/error messages above.

EXPECTED RESULT
No info/error messages when running `dolphin .`, new Services should be
installed when clicking install in Configure Dolphin, a way to see and manage
installed these Services and kdeconnectd should never be started without being
explicitly started by the user. 

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.14.5
KDE Plasma Version: 5.14
KDE Frameworks Version: 5.54.0
Qt Version: 5.11.3

Dolphin: 18.08

ADDITIONAL INFORMATION
Please don't just say that this is an old version of Dolphin. It's the latest
version in Debian's official repos so this issue is important anyway.
(Furthermore you could help to get a newer version into Debian's official repos
or set up a repo with newer KDE version for Debian 10 stable.)
