Comment 1 Roman Gilg 2018-05-22 17:31:39 UTC

The back trace is a bit empty (missing debug symbols). Can you install debug package for KWin? Thank you.

Comment 2 Martin Flöser 2018-05-22 19:18:08 UTC

Setting to needsinfo due to lacking debug symbols.

Comment 3 Roman Gilg 2018-05-24 07:27:24 UTC

*** Bug 394645 has been marked as a duplicate of this bug. ***

Comment 4 Fabian Vogt 2018-05-24 07:35:27 UTC

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?

Comment 5 Christoph Feck 2018-06-15 20:37:47 UTC

No response, changing status. If you can still reproduce this issue with a supported combination of KDE/Qt repositories, please add a comment.
