Same error for me. Every time I switch from a video to a photo I've got a segfault. Running on archlinux, Linux 4.6.4, gwenview 16.04.3
On MAGEIA 5 - KDE 4.14.15 - Gwenview 4.14.0 pre If a folder contains any video that gwenview doesn't like (in my case a XVID codec in a AVI container) it will crash (not responding) after displaying the first picture : ( in Konsole : gwenview(26255)/kdeui (kdelibs): Attempt to use QAction "edit_undo" with KXMLGUIFactory! processus stopped) If I remove these videos from the folder : it will display all other videos and pictures with no problem. If I put back one of these video in the folder : it will crash again on the first picture. I don't mind if gwenview can't display every codec. But it should NOT crash. SORRY BUT THE STATUS OF THIS BUG SHOULD BE CONFIRMED otherwise KDE won't improve.
