Version: (using KDE 4.3.1) Installed from: Gentoo Packages If I try to print gzipped SVG images using the PrintWizard, it "prints" blank space instead. Normal SVG prints fine.
Skimming thorugh the code, I found out that the QSvgPlugin (a QImageIOPlugin) does not associate svgz with itself, causing QImage::load() in TPhoto::loadPhoto() to fail. I have made a trivial patch to qt-svg that resolves this and filed it at Qt's Task Tracker (an id was nowhere to be found).
With new PrintCreator from digiKam core version 5.7.0, the problem is not reproducible. Gilles Caulier
