Comment 1 Aleix Pol 2018-06-21 14:40:02 UTC

I cannot reproduce.

Can you try running from a terminal? It's possible that it explains why it's crashing as the crash is in Qt.

Comment 2 Christoph Feck 2018-07-18 16:28:33 UTC

If you can provide the information requested in comment #1, please add it.

Comment 3 Christoph Feck 2018-08-02 17:22:54 UTC

To further investigate this issue, KDE developers need the information requested in comment #1. If you can provide it, or need help with finding that information, please add a comment.

Comment 4 Christoph Feck 2018-08-30 20:36:30 UTC
