Description of problem: On a machine upgraded from Fedora 20 (KDE 4) to Fedora 22 (KDE Plasma 5), inside KDE settings I selected desktop theme, then "get new themes". I have been asked if I wanted to migrate KDE Wallet. I selected "No, don't ask it again" and then instead of having a list of themes, I got an error message, that translated to English language should be something like this: "Unknown error in open collaboration API (0)" Reproducible: Always Version-Release number of selected component (if applicable): KDE framework version is 5.9
