Description Mahendra Tallur 2017-09-01 17:51:15 UTC
Hi ! 
Using KDE Neon (non-LTS), since KDE apps upgraded from 14.04.3 to 17.08.0, gwenview segfaults with a specific set of pictures.

Unfortunately, as those are private pictures (with pictures of children) I cannot make them public but I can give access to whoever asks.

What occurs : open any of those pictures with gwenview : pic is displayed.
Then hit spacebar to open the next one : instant segfault.

Here is a gdb trace : https://framabin.org/?260d1410e39184c1#UXye4waTiONmBaCE8VdbEaw3iI8jhNIhLymes/cx6gU=

Comment 1 Mahendra Tallur 2017-09-01 17:53:28 UTC
TYPO : I obiously meant : from 17.04.3 to 17.08.0.

Please note : I assumed it occurs since KDE apps 17.08.0 because I'm pretty sure I watched them recently with no segfault, plus I started a liveCD (manjaro) containing KDE apps 17.04.3.

Hi ! Thanks for the fast triaging !

I'm so sorry, I tend to file duplicates although I always check before :-(
