Thanks a lot for your work.

My problem is this: Suddenly we seem to support as a major file format .xcf.gz,
but not .xcf. Why? Because .xcf is loaded by a QImageIO plugin, .xcf.gz is
seemingly loaded by a custom loader, but in fact, it is a wrapper around the
QImageIO plugin (QIMAGE file format).
There are a number of KImgIO plugins,
http://websvn.kde.org/trunk/KDE/kdelibs/kimgio/
This would be the best place for this purpose!
Also have a look at 
http://api.kde.org/4.x-api/kdelibs-apidocs/kdecore/html/classKFilterDev.html
it may be possible to feed the compressed data directly via QIODevices in the
XCF imageio plugin (provided in kimgio as well).
