Version: 2.4 (using KDE 4.4.3)
Steps to Reproduce:
Run Gwenview in folder with many 18Mpx or so images. Pick up one image and scroll to next using mouse wheel.
After seeing 7…8 images top says Gwenview has allocated 21% of available memory on a system with 2G RAM and 1.5G swap, which means 400MB of RAM.
Gwenview allocated about 18*3 or 18*4 MB for 18Mpx image and a couple of MB for code, shared libs, etc.
Update on steps to reproduce (don't know how to edit bug):
On each image press middle button to see image in 1:1 and then again to go back to fit to screen.
Happens to me too, just viewing images in fullscreen mode totally hangs the machine with crazy disk usage.
This is a severe bug because crashes the whole system.
amd64 188.8.131.52 kernel
