Hello 

this is not a new bug.

there were same bug with 15.0  19.04.(0-1)and Wolfgang Bauer supplied an rpm in his opensuse repo which fixed it. i am surprise it is not fixed with 19.04.2

i must retrive the report i sent in the past.

*** This bug has been marked as a duplicate of bug 371511 ***

It was fixed with Qt 5.12.x, but the crashes seem to be back with Qt 5.13.
