Description Andi Clemens 2010-03-06 10:20:30 UTC 
Version:           unknown (using 4.4.1 (KDE 4.4.1), Arch Linux)
Compiler:          gcc
OS:                Linux (i686) release 2.6.32-ARCH

Some PNGs of mine are not able to use the "Equalize" autoCorrection filter.
See attached screenshot. 
According to "git bisect" the commit http://websvn.kde.org/?revision=1091019&view=revision is responsible for that issue.

Equalize not working
Comment 2 Johannes Wienke 2010-03-06 10:31:06 UTC 
I can confirm this also for jpegs. I think this isn't related to the file format at all.
Comment 3 Andi Clemens 2010-03-06 10:47:15 UTC 
I can only see it for this PNG, but it might be unrelated to the file format.

Andi, Johannes,

I never reproduced this problem on my computer.

Do you have an image to hack ?

Andi,

This file still valid using digiKam 2.x serie ?

If yes, can you provide a file to test in my computer ?
