Hi,
Yes problem is fully reproducible here. the Unit test from digiKam trying to load image report a message from the KImageIO XCF plugin as file is not recognized :
digikam.dimg: "cares-20170212-6640.xcf" : "QIMAGE" file identified
digikam.dimg.qimage: Can not load " "cares-20170212-6640.xcf" " using DImg::DImgQImageLoader!
digikam.dimg.qimage: Error message from loader: "Unable to read image data" <=====!!!!!!!
digikam.dimg: "cares-20170212-6640.xcf" : Unknown image format !!!
This i sa problem in the KDE plugin. The problem is the same for both shared files.
Note that Exiftool is able to load XCF metadata :
[gilles@localhost dimg]$ exiftool cares-20170212-6640.xcf

So, please report this problem to KDE bugzilla component "frameworks-kimageformats". Look like there are already some files open about XCF support, and especially when color depth is higher than 8 bits.
