Since upgrading to Qt-5.6.0-rc, some kio slaves fail to load, including plasma-workspce's desktop.so kio plugin. I see error: Could not start process: Unable to create io-slave: klauncher said: Error loading /usr/lib64/qt5/plugins/kf5/kio/desktop.so in the desktop containment I'm assuming this is some sort of Qt regression, since it didn't happen with Qt-5.6.0-beta, but thought I'd at least document it here too. Doesn't seem to happen with all kio slaves, in particular, file:/ still works ok. Not sure how to debug this.

Oh yay, seems problem solved after clearing ~/.cache/ content Now I wish I'd been more careful, to see what exactly it was.
