Basically what it says. Since last upgrade to 16.12 basically all KDE apps are complaining about ambiguous shortcuts. But it mostly annoying with dolphin. If more info is needed let me know. Or even how to reset it - i am using the default shortcuts. System: openSUSE 42.2
Can you attach a screenshot of the dialogs you get?
