Application: gwenview (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
Gwenview crashes reproducibly when switching the image http://imgs.xkcd.com/comics/the_pace_of_modern_life.png from "Fit" mode (the default) to "100%" mode (via the buttons at the bottom of the window).

- What I was doing when the application crashed:
$ wget http://imgs.xkcd.com/comics/the_pace_of_modern_life.png
$ identify the_pace_of_modern_life.png
the_pace_of_modern_life.png PNG 483x4160 483x4160+0+0 8-bit PseudoClass 256c 550KB 0.000u 0:00.010
$ gwenview the_pace_of_modern_life.png
-> Click on "100%" in Gwenview
-> Crash

The crash can be reproduced every time.

-- Backtrace:
