Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed: I am browsering photos in fullscreen mode. App crash after I try display another image. I mean I change folder before it, but I am not sure.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
