           Summary: endianess problem under Linux-PowerPC (with png images
                    at least)
           Product: digikam
           Version: 0.9.0-beta1
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: yannick.roehlly free fr

Version:           0.9.0-beta1 (using KDE 3.5.4, Debian Package 4:3.5.4-1 (testing/unstable))
Compiler:          Target: powerpc-linux-gnu
OS:                Linux (ppc) release 2.6.17

The new 0.9.0-beta1 (tested with up to svn 567816) may have an "endianess problem" under PowerPC with PNG images.

I'll try a attach screenshots to illustrate this bug (well, if it's possible as it's my first use of KDE bug report system) based on the Debian logo (http://www.debian.org/logos/openlogo-nd-100.png).

The generated thumbnails have wrong colors as shown in snapshot1.png.

When viewing the image, Digikam seems to have the same problem described in Krita bugs #125944 and #127296 (although this bug affected Krita a zoom levels other than 100% and here the bug seems not to be related to the zoom level).
The "alpha channel checker" is shown and the colors are wrong (or, as suggested in bug #125944, the blue channel is correctly displayed, but red and green are interpreted as alpha). The screenshot snapshot2.png shows the problem.
