Comment 1 Aleix Pol 2017-07-31 10:09:04 UTC 
Sería posible tener un backtrace con símbolos para el depurado (debugging symbols)?
No hay mucho que pueda hacer con esta traza.
Comment 2 Aleix Pol 2017-07-31 10:09:46 UTC 
Needs more information, I can't reproduce or understand what's going on.
Comment 3 Nate Graham 2017-10-19 21:54:43 UTC 
There's a better backtrace in https://bugs.kde.org/show_bug.cgi?id=385554
