Testing with Gwenview 17.12.0, Frameworks 5.40 and Qt 5.9.2, switching between images and also viewing CR2 files works fine for me. I can only assume this has been fixed somehow (looking at the backtrace, possibly indirectly in Qt). Nevertheless, please test again on a newer system and comment if it still crashes for you, then we'd need to reopen. In this case it would also be great if you could determine a particular file that is crashing Gwenview and attach it to this bug report.
