Fatal error: exception GdkPixbuf.GdkPixbufError(5, "Failed to load image '/usr/local/share/marionnet//images/launcher-icons/marionnet-launcher.png': Fatal error in PNG image file: IDAT: invalid distance too far back")

Hello,
this is due to a known problem with libpng :

https://github.com/glennrp/libpng/issues/125

this file (and others have been patched in the trunk version of marionnet

solution 1) reinstall marionnet with
./marionnet_from_scratch -m trunk
You will get a far better up to date version of marionnet and its components

solution 2) correct each broken png file with some tool like

pngcrush -fix -force old.png new.png

or

optipng -quiet -force -fix foo.png

JV: time for a new release (at least for these png files) ?
