Access SMB and WEBDAV from KDE Frameworks5

I know the workaround to access SMB and WEBDAV files is to

sed -i ‘s/X-GIO-NoFuse=true/#X-GIO-NoFuse=true/’ /usr/local/share/applications/libreoffice*

This is a work-around a long standing bug documented here:

However, as of LO Version:
Build ID: 1:5.2.4~rc2-0ubuntu1~xenial2
CPU Threads: 4; OS Version: Linux 4.4; UI Render: default; VCL: kde4;
Locale: de-AT (en_US.UTF-8)

added via deb xenial main


KDE Frameworks 5.30.0
Qt 5.7.0 (built against 5.7.0)

(Neon 5.8.5)

this no longer works. When I click in Dolphin on a WebDAV-shared file, the file get’s no longer opened in Writer / Calc / …

This is very, very, very, annoying, especially as I never managed to connect LibreOffice to WebDAV using the built-in dialogs.
