Testing current Qt (5.6.0-rc) copr, https://copr.fedorainfracloud.org/coprs/g/kdesig/Qt5/ plasmashell desktop containment fails to load with error: Unable to create io slave: klauncher said: Error loading /usr/lib64/qt5/plugins/kf5/kio/desktop.so reproducible trying desktop:/ url in dolphin too.
Fwiw, this problem seems new since -rc landed, -beta builds were fine in this regard
Pushed upstream to: https://bugs.kde.org/show_bug.cgi?id=360217 After confirming problem still happens with latest plasma/Qt-5.6 builds
Oh yay, seems problem solved after clearing ~/.cache/ content Now I wish I'd been more careful, to see what exactly it was.
I have this issue since more than a month now. Can you please give a hint how to find the reason for this? Clearing ~/.cache/ did not help.
