The back trace is a bit empty (missing debug symbols). Can you install debug package for KWin? Thank you.
Setting to needsinfo due to lacking debug symbols.
*** Bug 394645 has been marked as a duplicate of this bug. ***
That looks like either kwin hasn't built against the right libkdecoration or either of them built against a different Qt version than installed. Leap 42 neither ships Qt 5.10 nor Plasma 5.12.5 - how did you add those?
No response, changing status. If you can still reproduce this issue with a supported combination of KDE/Qt repositories, please add a comment.
