It's not bug, it's KDE system wide configuration I think.
It might be configurable in KDE probably.

System settings -> Keyboard & Mouse -> Standard Keyboard Shortcuts -> Type 
redo in the search bar

CTRL+SHIFT+Z is better short-cut, I know that people are used to CTRL+Y
to redo from Windows and maybe also in GNOME, but try to undo/redo/undo
with CTRL+Z and CTRL+SHIFT+Z and you will see why it is like that in KDE :)
Watch your fingers ;)
