Bug 354329

Application: gwenview (4.14.0 pre)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-38-generic x86_64
Distribution: Linux Mint 17.2 Rafaela

-- Information about the crash:
- What I was doing when the application crashed:
I was looking through a wallpaper dump torrent from reddit (https://www.reddit.com/r/pcmasterrace/comments/21xa6w/a_torrent_version_of_the_over_52000_wallpapers) and using Gwenview to tag the images. There was 38,000+ images in the folder which made things go slow. I launched Gwenview from the command line with "gwenview 006BRkX.jpg" to avoid having anything try to generate previews of the images. I had looked through and taged many of the images when Gwenview crashed. I have a copy of everything Gwenview echoed to console if you need it.


- Unusual behavior I noticed:
The program ran fairly slow when I first started it so I gave it some time to process whatever it needed to do and after a while it ran quickly. I noticed while using the program that as I tagged images many of the tags I applied did not show back up in the tag editor. Some would autocomplete while others had to be typed in again and again.

Looking at the console output at the time of the crash I did notice this:

I have a copy everything logged to console while running Gwenview if needed.  Also, I am using Gwenview as distrubuted with Mint 17.2 KDE. Up to date as of 9:00 on Oct 24, 2015.
