I had Shift+Tab combination set to the "Next Session" action. After full system upgrade pressing this combination in Yakuake pops out a 'An ambiguous key sequence' error. I tried opening Konsole's shortcuts and removed Shift+Tab action there, but that didn't helped. I also gone through every tab in "Global shortcuts" in System Settings with no success. STEPS TO REPRODUCE 1. Open 2 tabs in Yakuake. 2. Set "Next Session" to "Shift+Tab" 3. Try switching between tabs using this key combination.
I can confirm this. I have `Next Session` set as `Ctrl+Alt+Right` and it now gets reported as `An ambiguous key sequence`
