Tried to maximise Gwenview, which was showing a simple .JPG image. It maximised and immediately crashed. Using Kubuntu 16.10, KDE 5.26.0, Qt 5.6.1 and Gwenview 16..4.3. Here is the backtrace: Application: Gwenview (gwenview), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
